All the STAs are engaged in web browsing, which is characterized by a short file downloads over TCP, with short duration of inactivity or think time in between two file downloads. Under this traffic, Static PSM (SPSM) performs better than CAM, since the STAs in SPSM can switch to low power state (sleep) during think times while in CAM they have to be in the active state all the time. In spite of this gain, performance of SPSM degrades due to congestion, as the number of STAs associated with the access point (AP) increases. To address this problem, we propose an algorithm, which we call opportunistic PSM (OPSM). We show through simulations that OPSM performs better than SPSM under the aforementioned TCP traffic. The performance gain achieved by OPSM over SPSM increases as the mean file size requested by the STAs or the number of STAs associated with the AP increases. We implemented OPSM in NS-2.33, and to compare the performance of OPSM and SPSM, we evaluate the number of file downloads that can be completed with a given battery capacity and the average time taken to download a file.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130251191","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}

Clustering technique is one of the methods utilized to extend lifetime of the network by applying data aggregation and balancing energy consumption among sensor nodes of the network. In this paper, we propose the recently developed, Harmony Search Algorithm (HSA) for minimizing the intra-cluster distance and optimizing the energy consumption of the network. HSA is music based meta-heuristic optimization method which is analogous with the music improvisation process where musician continue to polish the pitches in order to obtain better harmony. A comparison is made with the well known cluster-based protocol approach developed for WSNs known as Low-Energy Adaptive Clustering Hierarchy (LEACH), heuristic optimization algorithms like Particle Swarm Optimization (PSO) and Genetic Algorithm(GA) as well as the traditional K-means and Fuzzy C-Means (FCM) clustering algorithms. Simulation results demonstrate that the proposed protocol using HSA can reduce energy consumption and improve the network lifetime.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127420977","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}

While taking the challenging healthcare requirements into account, this article aims at the study of energy consumption in BSN scenarios. For that purpose, the IEEE 802.15.4 MAC limitations are first examined and other potential MAC layer alternatives further explored. Our intent is to introduce energy-aware radio activation polices into a high-performance distributed queuing medium access control (DQ MAC) protocol and evaluate its energy-saving achievements, as a function of the network load. To do so, a fundamental energy-efficiency theoretical analysis for DQ MAC protocols is hereby for the first time provided. By means of computer simulations, its performance is validated using IEEE 802.15.4 MAC system parameters. The achieved outcome shows that the proposed DQ MAC scheme outperforms IEEE 802.15.4 MAC energy efficiency in all possible BSN scenarios.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452253","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 the United States, AFCI installation in bedroom receptacle outlets has been mandated since 2002. As AFCIs have been widely adapted to real situations, several kinds of AFCIs have been developed including branch/feeder, cord, outlet box, and portable designs. Using various types of AFCIs creates a hierarchy consisting of multi-level AFCIs such as a portable AFCI serially connected to an outlet box AFCI. This multi-level AFCI structure causes a serious problem by enabling an upper level AFCI to detect an arc fault occurring in the surveillance area of lower level AFCIs. This problem results in de-energizing the whole area covered by the upper level AFCI. In this paper, we propose a solution to the multi-level AFCI problem that occurs when several types of AFCIs are used in the same hierarchy. To provide a practical solution, we first present the theoretical background of a multi-level AFCI and suggest a solution that integrates collaborative communication and computing power into a conventional AFCI device. Finally, we introduce a prototype implementation of our approach. Our proposed approach can protect people and facilities against electrical fire hazards, which is one of major challenges that the smart grid aims to overcome using information technology.","PeriodicalId":422951,"journal":{"name":"2010 IEEE International Conference on Communications Workshops","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121286034","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}
