Existing methods focus on minimizing the use of communication resources, yet they are unable to exploit the availability of channel multiplicity for achieving shorter average delay time in TSCH networks. In this paper, we propose a new method to construct cost-balanced routing trees that can utilize multiple interfaces at the coordinator. Our simulation results show that the proposed method is able to achieve low-delay data collection in TSCH networks.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132122970","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}

Although some applications have been proposed to support traffic safety and transportation efficiency using Long Term Evolution (LTE) techniques, the security issues of the integration of LTE into the vehicular environments have less been addressed. In this paper, we propose a security framework over a public transport based heterogeneous wireless vehicular networks to face the challenges of malicious attacks in vehicular environments efficiently. We conduct security analysis and proof of logic correctness of the proposed schemes by formal logic. Besides, performance evaluation shows that the proposed authentication framework can efficiently reduce authentication time and number of hops during message relay by sharing key information.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134050571","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 the proposed scheme, the distributed source encoder sends the uniformly-spaced information bits together with the parity bits to simultaneously achieve both distributed compression and channel error correction. Moreover, iterative joint decoding is introduced to further exploit the source correlation. Simulation results show that the proposed DJSCC scheme can obtain relatively large additional coding gains and guarantee that the distributed source shows almost the same performance, which is suitable for equal error protection applications.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125150161","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}

However, most of existing research is developed under the Gaussian input assumption and few concerned the equipment probability finite alphabet input assumption which is more coincident with the widely adopted digital signal. This shortage limited the application of RA network in practical scenarios. For this reason, we formulate an energy efficient (EE) problem of RA network with amplify-and-forward (AF) protocol and develop a sub-optimal power allocation algorithm which is named constant proportion power allocation (CPPA) to solve it.

To solve the non-convex NP-hard optimization problem, the original problem is rewritten as a sparsity digital precoding optimization problem based on the predesigned analog precoder codebook. Then a convex sparsity inducing approximation method is used to transform the problem into a suitable semidefinite positive (SDP) problem. Finally, an effective algorithm is developed to solve the SDP problem of interest for the hybrid digital/analog MISO systems.

Each base station (BS) is equipped with M (unlimited) antennas serving K (large but finite) users. Further, we let τ (pilot length) be an arbitrary but small value. As such, pilot optimization is formulated as a multi-objective optimization problem (MOP). It is shown that, when power control is enabled, maximally spaced sequences solve a worst-case signal-to-interference (SIR) problem only under a special channel case, whereas the general channel case doesn't admit a simple solution. Motivated by the epsilon-constraint technique in MOP, we propose a low-complexity algorithm for optimizing pilots of different users from a fixed orthonormal basis in an iterative manner. For only a few iterations, the algorithm shows good convergence property, which is supposed to converge to a Pareto-optimal solution. The numerical results show that the algorithm gives rise to a significant improvement of the cell throughput as well as the per-user mean SIR and per-user mean rate.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114260766","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}

However, recent works prove that one third of the total energy consumed is wasted by keeping servers in comatose and almost half by keeping them in comatose and idle. To address this issue, we have developed an economic framework and a model based on the servers On-Off technique and semi-Markov Decision Process. This approach provides an optimal policy that minimizes data center's power consumption and maximizes the Cloud Provider's profit. The model allows updating dynamically the number of active servers in a data center according to the traffic.

Geo-location database can enable white space devices (WSDs) to make use of the vacant spectrum without harmfully interfering with incumbent services. Dynamic changes of the wireless environment pose significant challenges to the database approach. Wideband spectrum sensing can detect the instant spectral opportunities over the wide frequency range, but the high sampling rate is hard to implement in the power-limited devices. To relax the sensing requirements on the WSDs, hybrid framework that combines the advantages of both geo-location database and spectrum sensing is explored in this paper. To further reduce the sampling bottleneck at high frequency, sub-Nyquist sampling techniques are adopted by exploiting the sparse property of the wideband signals. The experimental results show that the proposed hybrid schemes can achieve improved detection performance with reduced hardware and computation complexity in comparison with the sensing and database only approach.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114364380","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}
