Sensing, processing and transmitting are the main contributors to energy consumption in a video sensor node. Among these, wireless transmissions play a dominant role. An effective way for reducing energy consumption is to adjust the active time duration of node's radio transmission. However, this method has the main drawback that affects streaming quality in terms of throughput and delay. So, one of the big challenges when designing an energy-aware VSN is the trade-off between energy consumption and video streaming quality. This paper proposes an Uplink Adaptive Multimedia Delivery (UAMD) scheme that dynamically adjusts the wakeup/ sleep duration of video sensor nodes based on the node remaining battery levels and network traffic conditions. The UAMD algorithm employs a utility function in the decision on duty cycle adjustment process. Simulation results show how UAMD achieves good balance between energy consumption and throughput in comparison with other duty-cycle-based schemes.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"28 1","pages":"85-90"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83632313","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}

Most of previous studies focus on scheduling mobile chargers efficiently for rechargeable sensor nodes. In this paper, we consider optimizing the deployment for Wireless Charging Stations (WCSs) in urban area. We respect the users detouring cost, when they need move to the candidate WCSs. Given a number of WCSs and users trajectories, we aim at optimizing the WCSs deployment to maximize the number of users for recharging with guaranteed probability. We convert our deployment problem into the weighted maximum coverage problem, which has been proved to be NP-hard. We have also proved that our objective function is a maximum submodular set function. Then a simple but efficient greedy algorithm could be applied with guaranteed approximation ratio (1−1/e ). Finally, we evaluate the performance of our algorithm by comparing with two effective algorithms, and the impacts of different parameters on our algorithm. The evaluation results show that our algorithm improves the number of covered users with 30% comparing with two aforementioned algorithms.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"150 1","pages":"493-497"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72688301","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}

Cellular technology relying on LTE-based standards has been identified as a promising option to support advanced distribution-grid operations with stringent communication requirements. In this paper, a reliability analysis of wide-area monitoring systems in cellular-enabled distribution grids is presented. The LTE random access channel (RACH) procedure enhanced with an access class barring (ACB) scheme is modeled via a Markov chain taking into account a realistic model of the varying traffic behavior of monitoring devices. Based on the proposed analytical framework, we derive the reliability expression which depends on various RACH and ACB parameters and the monitoring traffic characteristics. With the aid of extensive simulations, we validate the accuracy of our analytical model. Finally, a performance evaluation in terms of reliability is carried out under different network and traffic configurations and several insights can be drawn for the reliable support of monitoring traffic.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"65 1","pages":"724-730"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76425266","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, MTC applications have different characteristics and requirements compared with the services provided by legacy cellular networks. For instance, an MTC device sporadically requires to transmit a small data packet containing information generated by sensors. At the same time, due to the massive deployment of MTC devices, it is inefficient to charge their batteries manually and thus a long battery life is required for MTC devices. In this sense, legacy networks designed to serve human-driven traffics in real time can not support MTC efficiently. In order to improve the availability and battery life of MTC devices, context-aware device-to-device (D2D) communication is exploited in this paper. By applying D2D communication, some MTC users can serve as relays for other MTC users who experience bad channel conditions. Moreover, signaling schemes are also designed to enable the collection of context information and support the proposed D2D communication scheme. Last but not least, a system level simulator is implemented to evaluate the system performance of the proposed technologies and a large performance gain is shown by the numerical results.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"69 5 1","pages":"1011-1017"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73350613","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 various technologies to enable network connectivity, Long Term Evolution (LTE) is by far the most ubiquitous technology to provide coverage for IoT devices. The IoT devices are inherently resource constraint and efficient communication is one of the primary requirements of these devices. LTE Random Access Channel (RACH), one of the primary procedures to enable channel access for devices, is well suited for cellular deployment. In this work, we have demonstrated that the current LTE-RACH procedure is not power efficient for dense deployments because in such scenarios RACH failures are mostly due to request collisions and increasing the transmit power does not give any significant advantage. We have also proposed Delayed Power Ramping Algorithm (DPRA), a heuristic based approach to improve the energy footprint of the IoT devices. We have conducted extensive simulations using Network Simulator (ns3) and discussed the performance results of the proposed approach for different scenarios.","PeriodicalId":6656,"journal":{"name":"2017 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":"33 1","pages":"373-378"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75035820","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}
