However, power consumption is increased significantly when many antennas are used. As importances of economic and environment benefits have arised, consumed power have to be handled through maximizing energy efficiency (EE). EE can be increased using antenna selection which can reduce power consumed in radio frequency (RF) chains. On the other hand, there is a limited space to integrate many antennas. Integrating many antennas in fixed space causes significant quantities of mutual coupling and spatial correlation between antennas. Therefore, mutual coupling and spatial correlation have to be considered when EE is maximized through antenna selection in practical system. In this paper, antenna selection algorithm is proposed considering mutual coupling and spatial correlation between antennas in the situation where antennas are integrated in fixed space. Mutual coupling and spatial correlation are reflected by electromagnetic (EM) simulation tool to consider more practical system. Then, performance of the proposed antenna selection algorithm is analyzed compared to three methods which are exhaustive search method, conventional algorithm and random selection method. Also, performances of the proposed algorithm are investigated in different environments where channel condition is different and minimum rate is required.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132859959","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}

It allows secondary users to opportunistically access and re-use the spectrum resources under-utilized by licensed or primary users. Spectrum sensing (either cooperative or non-cooperative modes) is exploited to identify those unused (free) frequency bands. This new technology has been proved to be vulnerable to an increasing number of attacks, such as Byzantine attacks. Here, we propose a novel reputation-based cooperative spectrum sensing method that first detects, and then rejects any malicious secondary user, thus improving the system performances. We evaluate the error probabilities (detection vs. false alarms) of the system, as well as the number of both correctly identified attackers and discarded honest users. Finally, we compare our method to a recently published reputation-based method (either blind or non-blind). As shown by the simulation results, the proposed method outperforms the conventional approach, confirming its robustness in detecting different types of Byzantine attacks.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131298963","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}

Limited frequency resources are shared by a large number of UEs, and complex interference is introduced due to resource sharing between uplink, downlink UEs and D2D links. To manage the resource and achieve the maximum total system capacity, a non-deterministic polynomial (NP) hard optimization problem is formulated. To efficiently solve the problem, a Graph based Two-step Resource Allocation (GTRA) algorithm is proposed. In the first step, a full duplex base station (BS) allocates resources to half duplex uplink and downlink UEs by a graph coloring based algorithm. The second step is a bipartite graph based Multi-Stage Matching (MSM) algorithm to allocate resources to D2D pairs. The GTRA algorithm can effectively allocate the spectrum resources with low complexity while guaranteeing the Quality of Service (QoS) of cellular UEs as well. Simulation results show that our proposed algorithm performs better than the reference algorithms.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115803141","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}

Thus, there is a strong interest in developing energy efficient transmission techniques. In this paper, we present a new approach to minimize the energy consumption of clustered wireless sensor networks, while achieving the required level of reliability. We consider clusters where sensors transmit monitored data to nearby cluster-head using cooperative communication. The goal of our approach is to minimize the transmit power energy based on Bit Error Probability (BEP) criterion for selective digital relaying (SDR) schemes whose closed form expression was recently derived in previous works. Therefore, the proposed scheme can efficiently allocate the least transmission power among the source and the relays that satisfy the predefined level of reliability while decreasing the energy consumption of the node. Simulation results show that our relay selection algorithm achieves significant energy savings (more than 50% compared with direct transmissions for moderate SNR values and up to 90% in high SNR regions).","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114335272","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 C-RAN, all baseband signal processing is centralized at one Baseband Unit (BBU) pool powered by cloud computing technologies. Whilst the Remote Radio Heads (RRHs), left off on the cell sites, are connected to the BBU pool through fronthaul networks and can be densely deployed with low cost. However, a large number of active RRHs located close to each other may result in severer interference and inefficient energy consumption. To tackle above challenges, we formulate a network power consumption minimization (NPCM) problem, which selects a set of active RRHs and constructs the user association with the active RRHs. The capacity limitation of the fronthaul network is considered in the problem. Since the NPCM problem belongs to the integer programming problem and is NP-hard, we propose a low complexity approximation algorithm that yields the performance guarantees: joint RRH selection and user association (JRSUA) algorithm. A simulation platform is developed to evaluate the network power consumption in three fronthaul network scenarios: fiber, wireless and mixed. Simulation results show that the proposed JRSUA algorithm is able to provide near-optimal performance with reduced complexity and outperforms the other counterparts.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115987133","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}
