A particularly interesting family of distributions are the binomial/multinomial distributions. Existing approaches resort to sliding windows that track changes by discarding old observations. In this paper, we report a novel estimator referred to as the Stochastic Discretized Weak Estimator (SDWE), that is based on the principles of Learning Automata (LA). In brief, the estimator is able to estimate the parameters of a time varying binomial distribution using finite memory. The estimator tracks changes in the distribution by operating on a controlled random walk in a discretized probability space. The steps of the estimator are discretized so that the updates are done in jumps, and thus the convergence speed is increased. The analogous results for binomial distribution have also been extended for the multinomial case. Interestingly, the estimator possesses a low computational complexity that is independent of the number of parameters of the multinomial distribution. The paper briefly reports conclusive experimental results that demonstrate the ability of the SDWE to cope with non-stationary environments with high adaptation rate and accuracy.","PeriodicalId":125988,"journal":{"name":"2012 International Conference on Computing, Networking and Communications (ICNC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121379021","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}

The former has evolved to improve energy efficiency and resilient operation, yet true scalability has only been recently probed and quite sparsely advanced. Moreover, the traditional approach, whereby most WSN platforms are tailored for a single-application, imposes significant rigidity in re-utilizing platforms for new applications, and limitations on re-using previously deployed ones. In remedy, we present a novel paradigm in WSNs to efficiently utilize network resources, and extend it to a platform for multiple applications to cross-utilize resources over multiple WSNs. We present the approach in three phases; the first calibers resources in the network and their usability. Then applications are represented as finite sets of functional requirements. Finally, we present an optimization approach to find an optimal mapping between applications and resources. This paradigm presents a leap in scalability, not only in a WSN but across multiple ones, dynamically accommodating varying resources being introduced and removed; in addition to utilizing transient resources in their vicinity. To this end, we present an architecture to efficiently adopt WSNs in IoT with changing demands and scale. Our approach is further explained and demonstrated via a detailed use case depicting the premise of IoT applications.","PeriodicalId":125988,"journal":{"name":"2012 International Conference on Computing, Networking and Communications (ICNC)","volume":"660 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115123251","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 these infrastructures are prone to large scale outages due to disasters or faults, a resilient and survivable communication architecture is desired. In this work, we propose a resilient and survivable hierarchical communication architecture for the smart grid that mirrors the hierarchy of the existing power grid. Post-disaster resilience in grid communication is achieved through the grid flattening process. This process involves smart-meters and other disaster surviving elements of higher system levels of the grid forming a wireless mesh network. The flattened network of grid elements with one-hop communication links help in reliable and timely relaying of grid's health information to working regions of the grid. This allows for swift action by control engineers of the utility provider and emergency services with real-time data. We propose analytical models to study the performance of the flattened architecture as a function of outage area, smart-meter density and smart-meter's neighborhood size. The results from the analytical model will be compared with simulation results from OPNET.","PeriodicalId":125988,"journal":{"name":"2012 International Conference on Computing, Networking and Communications (ICNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128721253","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}

Many efforts have been done to better exploit multiple non-overlapped channels. However, due to the limited number of orthogonal channels in IEEE 802.11 b/g standards, using only non-overlapping channels cannot completely eliminate the interference. Recent studies indicate that we can improve the full-range channel utilization and the network throughput by properly utilizing the partially overlapping channels. However, there are only limited studies of channel assignment algorithms for partially overlapping channels. In this paper, we investigate the problem of partially overlapping channel assignment to improve the performance of 802.11 wireless networks based on SINR model. Using the SINR model, we deduce a direct relationship between maximizing system throughput and minimizing total interference when partially overlapping channels are employed. After that, we propose a greedy method to minimize the total interference for throughput maximization. We evaluate our algorithm through extensive simulations and compare its performances with those of the state-of-the-art.","PeriodicalId":125988,"journal":{"name":"2012 International Conference on Computing, Networking and Communications (ICNC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116305888","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}
