Therefore, mechanisms for minimizing traffic from cruising directly affect the dynamics of traffic congestions. One way to minimizing cruising traffic is efficient car-parking-slot assignment. Usually, the related design problems are combinatorial and the worst-case complexity of optimal methods grows exponentially with the problem sizes. As a result, almost all existing methods for parking slot assignment are simple and greedy approaches, where each car or the user is assigned a free parking slot, which is closer to its destination. Moreover, no emphasis is placed to optimize any form of fairness among the users as the a social benefit. In this paper, the fairness as a metric for modeling the aggregate social benefit of the users is considered. An algorithm based on Lagrange duality is developed for car-parking-slot assignment. Numerical results illustrate the performance of the proposed algorithm compared to the optimal assignment and a greedy method.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114402475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sub-Nyquist sampling has attracted significant interests for wideband spectrum sensing, while existing algorithms can only work for sparse spectrum with high computation and hardware complexity. In this paper, we propose a novel sub-Nyquist wideband sensing algorithm that can work for the non-sparse spectrum without sampling at full bandwidth through the use of multiple low-speed Analog-to-Digital Converters (ADCs) based on sparse Fast Fourier Transform (sFFT). The proposed permutation and filtering algorithm achieves the wideband sensing regardless of signal sparsity with low hardware complexity. In contrast to existing sub-Nyquist approaches, the proposed wideband sensing algorithm subsamples the wideband signal, and then directly estimates its frequency spectrum. The mathematical model of the proposed sub-Nyquist wideband sensing algorithm is derived and verified by numerical analysis over TVWS signals. The proposed algorithm shows considerable detection performance on wideband signals as well as reduces the runtime and implementation complexity in comparison with conventional wideband sensing algorithm.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123585518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we assume that the network employs superposition coding at the physical layer in order to implement multi-packet transmission. While most studies on superposition coding assume that unbounded number of packets can be coded together, physical and MAC layer limitations restrict the number of concurrent packets in a transmission set. Taking this constraint into consideration, we formulate the minimum delay scheduling as a combinatorial optimization problem and study its computational complexity under different transmission set sizes. We show that, when the transmission set size is limited to 2 packets, the problem can be solved optimally in polynomial time. Moreover, while the complexity of the problem for larger transmission set sizes is unknown, we present close-to-optimal heuristic algorithms that compute efficient solutions for the problem in polynomial time. Numerical results are also presented to study the efficiency and utility of the presented scheduling algorithms. Our results show that the heuristic algorithms are highly efficient, achieving delays that are less than 2% away from the optimal values.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123598740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multi-hop inter-vehicular communication is exploited for the purpose of establishing a path between S and D along which downstream cooperative vehicles serve intermediate packet relays. The formation of such a path is governed by the vehicular traffic behaviour as well as the per-hop contention-oriented data forwarding process. Following the formation of a continuous chain of in-range cooperative vehicles between an arbitrary source-destination pair (S,D), a stochastic analytical framework is developed with the objective of determining the probability of successful data transfer from S to D taking into account the per-hop vehicle contentions for channel access. Then, theoretical expressions for the achievable per-hop as well as the end-to-end throughput are presented. Simulations are conducted for purpose of validating the presented analysis and evaluating the considered subnetwork's performance.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124916978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To guarantee video fluidity, mobile video streaming is known to require a large bandwidth overhead with respect to the net encoded video rate. The quality of a received video stream is impacted by variations in the size of the transmitted video packets (chunks), and by statistical fluctuations in the data rate at which the allocated downstream wireless channel operates. First, in considering an illustrative video scenario, we show that the chunk size distribution is heavy-tailed, and is well fit by a Gamma distribution. Second, we employ a HAS based proxy video manager and resource controller at the base station node. Based on the channel quality observed and reported by a mobile client, the manager selects the proper channel bandwidth and data rate levels at which to transmit the stream's chunks, in accordance with the selected encoded video rate and the configured Quality of Experience (QoE) level at which the user is targeted to receive the video stream.The communications data rate is also set to assure an acceptable low video reception stall probability. To illustrate the performance of such a dynamic bandwidth allocation scheme, we compare it with an operation that employs a stationary setting of the channel bandwidth, and we compute the gain achieved when such adaptations are performed at the base station node on a chunk by chunk basis. We show by analysis, and confirm by simulations, the improvements achieved in the system's performance behavior through the use of the adaptive resource allocation scheme.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122656980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, broadband wireless infrastructures may be found in many rural areas for communications in specific sectors such as health or education services, environmental monitoring, etc. These sectorial broadband communications infrastructures are often multi-hop wireless networks using long-distance WiFi links or WiMAX. We propose the possibility of 3G operators sharing those third parties' infrastructures. It would permit them to have a low-cost backhaul solution for their rural 3G cells in those areas where the expected demand of 3G services does not ensure enough revenues to justify the deployment of dedicated infrastructures. This is a win-win solution because bandwidth-renting may help to achieve financial stability for such sectorial networks, while operators can extend their coverage to regions where this would not be economically sustainable otherwise. This paper studies the technical feasibility of the proposed solution. Different multi-hop broadband rural networks are studied, and a general architecture is derived from them. Then, additional requirements are introduced in order to make such networks support the QoS requirements of 3G voice and data traffic. Three techniques are considered in order to manage the network in such a way that 3G traffic and other traffics may be transported together in the network without compromising the quality of the backhaul: DiffServ, plain MPLS and MPLS-TE. Measurements taken on a real testbed in a laboratory allow us to compare the performance achieved with these three techniques, and the advantages and drawbacks of each of them are presented.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121147466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, providing service guarantees in dynamic channel conditions typically requires a cost in terms of spectral efficiency of the transmission resource allocation. In this work, we investigate this tradeoff and propose a resource allocation scheme that adapts the service level guarantees to the average channel conditions of the users, in order to provide fair resource allocation among users with homogeneous channel conditions, while improving the cell spectral efficiency. A performance analysis is carried out by comparing the proposed scheduler with other well known schedulers. Results show that the proposed method can improve the cell capacity, while guaranteeing long-term throughput fairness among users of the same class. In addition, we analyze the short-term throughput provided by the proposed scheduler and provide a semi-analytical model to assess the gap with respect to the long-term performance.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126982238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to be energy efficient, mobile robots should be deployed and controlled in such a way as to minimize travel distance. To do this, we examined multiple deployment and movement policies and their effects on the performance of a network. We tested three different deployment schemes and analyzed the results. We also analyzed the expected distance to each event to discover what, if any, effects the initial deployment has on that metric and in turn compared this to our results. We then tested three different collection methods and analyzed their performance. Next, we added service times to our model and lastly we changed the distribution of events to examine how these changes affected the network performance. Through our extensive simulations and mathematical analysis, we found a random deployment to be the most effective deployment policy with respect to computation time and network performance. Our proposed location prediction policy was also able to improve network performance, even over the collect and stay policy as shown through our simulations.","PeriodicalId":221796,"journal":{"name":"2015 IEEE 16th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"1983 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128045916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
