The architecture of small cells is still under discussion, various architectures have been proposed based on potential use cases. One of the most important use cases is to deploy small cells on a different frequency than that of the macro cell to offload traffic. Small cell discovery in this type of inter-frequency scenario is an open research problem. Aggressive scanning mechanisms may result in faster discovery of small cells and higher user throughput as well as higher macro cell capacity due to potentially increased offloading opportunity. However, frequent scanning may also result in higher power consumption for the device. Therefore, a tradeoff between offloading opportunity and device power consumption seems inevitable in practice. In this paper, we analyze the trade-off between the offloading capacity and device power consumption due to inter-frequency scanning mechanism for small cell discovery. Our findings show that although increasing the frequency of inter-frequency scanning does result in increased power consumption due to scanning, it actually lowers the total power consumed by the device since it leads to offloading to small cells, where the device consumes less overall power due to better coverage.","PeriodicalId":170309,"journal":{"name":"2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975729","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}

GWC may represent a breakthrough in the research areas of wireless on-chip communications, i.e., among the different processors or cores of a chip multiprocessor, and of these cores with the memory system. The main advantages of the resulting Graphene-enabled Wireless Networks on-Chip (GWNoC) are twofold. On the one hand, the potential of GWCto radiate in the terahertz band provides a huge transmission bandwidth, allowing not only the transmission of information at extremely high speeds but also the design of ultra-low-power and low-complexity schemes. On the other hand, the size of graphennas can be greatly reduced with respect to metallic antennas with the same resonant frequency, allowing the integration of graphennas within individual processing cores and the implementation of core-level wireless communication. In addition to these physical layer advantages, GWNoC represent a clear opportunity from the multicore architecture perspective. Due to their native implementation of broadcast and multicast communications, GWNoC will enable not just the alleviation of the latency or power bottlenecks of traditional on-chip networks, but also the devising of novel multicore architectures.","PeriodicalId":170309,"journal":{"name":"2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134422464","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}

Among them, the residential distribution transformer is considered as one of the most important components in the grid. The ageing of the transformer is closely related to the temporal evolution of the hot-spot temperature (HST), which is induced by the operating load level history. We propose an optimal control approach to obtain a new EV charging algorithm: the novel aspect of this algorithm is that it takes inertial behavior of HST into account, which is the key parameter to capture the ageing. Though our formulation closely resembles to the linear quadratic control problem that includes costs induced from the state of the transformer and its present charging load, the natural constraints which are imposed to the instantaneous charging level (saturation constraints) induces intricate complicacy for the analytical solution. Thus, we follow the Pontryagin maximum principle approach to obtain the optimal charging policy and resort to numerical methods to compute the optimal charging trajectory. Numerical results allow us to evaluate and compare the performance of the proposed algorithm with various existing benchmark charging policies.","PeriodicalId":170309,"journal":{"name":"2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116894514","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 this paper, we propose a heterogeneous network where multiple tiers of small-cells are deployed which in turn expand the network coverage and increase the frequency reuse distance without compromising the frequency reuse factor. The resultant network is referred to as K-tier HetSNets, where small-cells are padded between the macrocells such that each of the macrocells in the network employs aggressive frequency reuse scheme, i.e., same set of frequencies is used in each macrocell. It has been shown that the co-channel interference due to neighboring macrocells has been reduced significantly without increasing the frequency reuse factor. The large scale deployment of the small-cells may increase the downlink power consumption of the considered HetSNet. Therefore, we show that the population of small-cells in each of the K-tiers is probabilistically dependent on the traffic load due to active mobile users, such that the small-cells in the network turn on their sleep mode under low and medium traffic load during the day. Several simulation results are included to illustrate the impact of the aggressive frequency reuse scheme and traffic load dependent population of small-cells on the system interference and downlink power consumption of the small-cell base stations.","PeriodicalId":170309,"journal":{"name":"2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115239363","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}

The joint utilization of the existing wireless interfaces facilitates the development of advanced techniques to boost the performance of wireless networks and enhance the experience of mobile users. Among these techniques is device-to-device cooperation where a smartphone receives content from a base station on a given wireless interface and distributes it to other devices in its vicinity via another wireless interface. Another technique is traffic offloading in heterogeneous network scenarios where a smartphone downloads content using multiple wireless interfaces. In this paper, we study the readiness of high-end smartphones to utilize multiple wireless interfaces simultaneously focusing on capabilities and challenges.

All transceivers are equipped with multiple antennas exploited for spatial multiplexing. Instead of limiting the study to the total sum rate, we analyze the complete achievable rate regions of the two directions. We also take into account the effects of mismatched decoding at the receivers due to imperfect knowledge of the transceiver impairments. The analysis is conducted in the large-system limit using the replica method from statistical physics, which allows to encompass arbitrary channel input distributions. The analytical results characterize the effect of self-interference at the access point and inter-device interference on the achievable rate regions.

In this paper, we design a simple greedy link scheduling policy for networks in which every transmitter node has an associated long term-average energy constraint. We show that a policy that greedily switches the transmitter node off is sufficient to yield a good throughput performance by characterizing its performance using the Local Pooling Factor (LPF), a parameter previously used to characterize the performance of Greedy Maximal Scheduling (GMS) in wireless networks. We then demonstrate via numerical experiments that for a network in which links originally use a fixed transmit power, a joint greedy scheduling and power control policy that uses two transmit power levels consumes lesser average transmit power compared to Greedy Maximal Scheduling (GMS), while exhibiting similar throughput performance as that of GMS. Through these results, we establish how greedy scheduling can be combined with power control to obtain provable throughput performance guarantees, while also satisfying long term average power constraints in wireless networks.","PeriodicalId":170309,"journal":{"name":"2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130494483","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}

Since LTE networks are primarily designed and optimized for human to human (H2H) communications, existing protocols and mechanisms are not very efficient for supporting M2M communication. Several modifications are needed to address the service requirements and traffic characteristics of M2M devices in these networks. Device power efficiency is one of the crucial requirements for M2M communication. We focus on solutions to decrease power consumption of M2M devices over 4G networks. M2M traffic characteristics are different from those of H2H traffic in terms of the size and the frequency of the generated data. One possible mechanism is to maximize the time that the M2M device is in low power state. In this paper, we evaluate the impact of extending the Paging Cycle and reducing the RRC Connected-to-Idle transition tail time on power savings. Our results show that for infrequent data transmission extending Paging Cycle reduces power consumption up to 79.3%. However, for frequent data transmission reducing Connected-to-Idle transition tail time is more effective and reduces power consumption by up to 76.2%.","PeriodicalId":170309,"journal":{"name":"2013 First International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125707373","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}
