In particular, a progressive localization scheme is proposed that does not necessitate the need for any cluster as most existing schemes do. Initialization is done by generating a quadrilateral of sensor nodes where the connectivity weight between them is computed based on the estimated distance from a reference point, which may be any vertex of the quadrilateral. Distances between sensor nodes are mapped from a path-loss model that is governed by the NLOS and Rayleigh fading models, considering noisy communication channel. With the initial quadrilateral characterized, the other sensor nodes are localized in a progressive manner based on the same mapping model. Errors due to presence of obstacles and noisy channel are reduced by studying the estimated distances contributed from the neighboring sensor nodes. Efficiency of our proposed scheme is measured in terms of total power dissipation for localization and the total degree of neighboring nodes required for error reduction. Apart from simulation experiments, we verify our proposed scheme using real hardware deployment in both indoor and outdoor environments. Results reveal that the proposed scheme improves localization precision substantially.","PeriodicalId":123586,"journal":{"name":"2015 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127612807","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 the current communication technologies heavily rely on the backbone network, the failure of base stations (BSs) due to natural disasters or malevolent attacks causes communication difficulties for public safety and emergency communications. Recently, the use of unmanned aerial vehicles (UAVs) such as quadcopters and unmanned gliders have gained attention in public safety communications. They can be used as unmanned aerial base stations (UABSs), which can be deployed rapidly as a part of the heterogeneous network architecture. However, due to their mobile characteristics, interference management in the network becomes very challenging. In this paper, we explore the use of UABSs for public safety communications during natural disasters, where part of the communication infrastructure becomes damaged and dysfunctional (e.g., as in the aftermath of the 2011 earthquake and tsunami in Japan). Through simulations, we analyze the throughput gains that can be obtained by exploiting the mobility feature of the UAVs. Our simulation results show that when there is loss of network infrastructure, the deployment of UABSs at optimized locations can improve the throughput coverage and the 5th percentile spectral efficiency of the network. Furthermore, the improvement is observed to be more significant with higher path-loss exponents.","PeriodicalId":123586,"journal":{"name":"2015 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121341768","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 achieve the goal of energy saving, base station sleep schemes are extensively investigated; however, they are hard to implement in actual commercial network for the risk of losing of users. So in this paper, we try another way to improve the energy efficiency of LTE network by interworking with low energy consuming WiFi networks. Firstly the characteristics of the resource assignment in LTE and WiFi network are analyzed. The energy efficiency of eNodeBs and the degree of user satisfaction are defined as the optimization objections of the load balancing between LTE and WiFi networks. Then it introduces the edge users' handover requirements needed to be satisfied during the load balancing process. Following these conditions, the detailed load balancing algorithm is designed based on the adjustment of signal quality offset. The final simulation experiment verifies that the proposed load balancing algorithm can effectively balance the resources utilization in the LTE and WiFi interworking networks and the energy efficiency of eNodeBs can be improved by 13.11% compared with the case before load balancing with guaranteed user satisfaction.","PeriodicalId":123586,"journal":{"name":"2015 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123034837","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, it is difficult to identify the transmitter when several systems are sharing the spectrum in the same time. In order to improve the spectrum utilization, the spectrum shared by the secondary users may be detected as idle spectrum with keeping the detection performance of primary system. In this paper, we propose an identified primary sensing method by using cooperative sensing of ED and statistical information of primary. In system model, status of PU can be OFF and ON. Furthermore, SU can also share the spectrum while gives no interference to PU. In the proposed algorithm, we exploit the statistical information database, in which the average received power of primary system has been restored, and real-time observed power at surrounding sensing nodes to detect the recent test statistic. Our proposed algorithm is validated by computer simulation and results showed that in coexisting environment of primary and secondary systems, cognitive radio user can accurately detect the primary system under the existence of the secondary system.","PeriodicalId":123586,"journal":{"name":"2015 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115508695","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}

Enabled by such occupancy monitoring capabilities, there are extensive opportunities for improving the energy consumption of buildings via smart HVAC control. In this respect, the major challenges we envision are 1) to achieve occupancy monitoring in a minimally intrusive way, e.g., using the existing infrastructure in the buildings and not requiring installation of any apps in the users' smart devices, and 2) to develop effective data fusion techniques for improving occupancy monitoring accuracy using a multitude of sources. This paper surveys the existing works on occupancy monitoring and multi-modal data fusion techniques for smart commercial buildings. The goal is to lay down a framework for future research to exploit the spatio-temporal data obtained from one or more of various IoT devices such as temperature sensors, surveillance cameras, and RFID tags that may be already in use in the buildings. A comparative analysis of existing approaches and future predictions for research challenges are also provided.","PeriodicalId":123586,"journal":{"name":"2015 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123679108","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}

A soft end-toend solution from the core network to the radio access network, as well as the air interface is envisioned as the key to meet the extremely stringent demands. This paper presents our perspective of the 5G air interface and raise the concept of software defined air interface (SDAI) as a framework of 5G air interface. Instead of a global optimized air interface for the previous communication generations, SDAI is envisioned to bring agility and heighten the efficiency into the design and implementation of the building blocks of the air interface. The fundamental building blocks and the related parameters including spectrum, bandwidth, multiple access schemes, waveform, and so on, are all tunable such that the air interface can be optimized to each individual application scenario. To clarify the adaptation mechanism of SDAI, we provide a case study on the link adaptation between the sparse code multiple access (SCMA) scheme and the orthogonal frequency division multiplexing access (OFDMA) from energy efficiency and spectral efficiency co-design perspective.","PeriodicalId":123586,"journal":{"name":"2015 IEEE Wireless Communications and Networking Conference Workshops (WCNCW)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125580210","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}
