A VMNO in WNV pays the MNOs for leasing wireless resources and receives payments from its mobile subscribers (MSs) based on the qualities of communication services. In this paper, we propose a novel two-stage spectrum leasing framework to maximize the average profit of a VMNO. Specifically, a VMNO can first make long-term spectrum lease based on the prediction of the average user traffic intensity over a long time period. Besides, the VMNO can flexibly make additional short-term leases based on the actual realizations of MS locations. We adopt a general alpha-fairness utility function to evaluate the qualities of downlink services to MSs. Within the proposed framework, we derive a closed-form expression for the optimal short-term leasing strategy for the VMNO, based on which we then propose an efficient algorithm to calculate the optimal long-term lease strategy. Simulation results show that the proposed two-stage spectrum leasing strategies can effectively increase the profit of VMNOs.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"196 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":"132023305","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, two related scenarios are considered: max-min signal-to-noise ratios (SNR) in wireless multicasting and max-min power in wireless power transfer (WPT). The conventional approach recasts the original nonconvex problems into convex semidefinite programming (SDP) by applying semidefinite relaxation (SDR) technique. This approach directly optimizes the transmit beamforming vector, thus suffers from high computational complexity when the number of transmit antennas at the base station (BS) is large. In this paper, we propose a unified and optimal beamforming structure which is expressed as a linear combination of the channel vectors of all users. With this proposed structure, the problem of beamforming design is thus simplified to optimize the combining weight vector, the dimension of which equals the number of users. This indirect optimization can significantly reduce the computational complexity of the transmit beamforming design, especially for massive MIMO systems. Numerical results show that by using the proposed beamforming structure, the complexity of indirect optimization is significantly reduced without suffering performance degradation, compared to the conventional direct optimization.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"56 90 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":"128840189","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}

Our design objective is to maximize the minimum harvested energy of all the receivers by jointly optimizing the transmit beamforming vectors and the power splitting ratios while guaranteeing the signal-to-interference-and-noise ratio (SINR) and total transmit power constraints. The aforementioned max-min problem is non-convex due to the existing of infinite number of constraints, and thus it is difficult to solve. To tackle it, we first convert it into an easier non-convex problem with finite constraints by using some certain transformation techniques. Then, with the aid of the semidefinite relaxation (SDR) technique, we further obtain a relaxed semidefinite programming (SDP) problem, which is convex and thus can be solved efficiently by using interior point methods. Finally, simulation results are provided to validate the robustness and effectiveness of the proposed scheme.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"31 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":"126671878","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}

Providing location privacy for such an asset is tantamount to protecting the location of a source node from an attacker who is attempting to locate it. Although no solution exists to provide source location privacy over an extended period, it has been shown that attackers can be sufficiently inhibited by prominent approaches that use either a phantom node, via which protocol messages are routed, or nodes assigned to be fake sources, each of which then broadcast fake messages. However, the applicability of fake source approaches to networks where location privacy must be maintained for multiple sources has yet to be considered. This paper addresses this issue by analysing a representative fake source algorithm in the context of multiple sources, presenting simulation results that demonstrate the shortcomings of the approach and identifying the underlying limitations to pave the way for the development of algorithms capable of accounting for multiple sources.","PeriodicalId":282352,"journal":{"name":"2016 IEEE International Conference on Communication Systems (ICCS)","volume":"18 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":"123030245","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}
