It is vital to reduce energy consumption to improve lifetime of wireless sensor network. A proficient way to improve lifetime is to partition sensor network into groups called cluster with high energy node acting as leader of the cluster called cluster head. Cluster head is responsible for managing intra-cluster and inter cluster communication. Energy level of cluster head at a given point of time determines life of cluster and thereby whole sensor network. Failure in the cluster head brings cluster communication to halt and may require re-clustering to get sensor network back on track. These activities involve additional energy expenditure and ultimately possess great impact on lifetime of sensor network as a whole. To balance energy consumption among the cluster heads this paper proposes to have cluster of cluster heads within the cluster of sensor nodes. Given a moment, one cluster head act as master of the given cluster and the master-ship is rotated among cluster heads after specified number of rounds of communication. This improves the energy utilization of sensor network, maximizes the network lifetime and makes the wireless sensor network fault tolerant to some extent.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115731271","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}

We consider a distributed learning algorithm arisen in the context of CRNs. There are multiple distributed SUs searching for idle channels temporarily unused by the primary network. Optimal MAC is also analyzed with multiple channels and multiple secondary users (SUs). MAC solution for cognitive radio can also be implemented by the perfect and imperfect learning scheme. Perfect or partially observed Markov decision process (POMDP) framework is suitable when the PU's transition probabilities are known or partially known to the SUs. But in the CRNs, SUs are not exactly aware about the presence of the primary user's transmission in the particular spectrum band. So, imperfect learning model is also proposed for these type of unknown transition probability of primary users. Both perfect and imperfect learning is considered with and without the acknowledgement by the receiver. This MAC technique optimizes SU access policy while protecting PU performance. This paper also try to design optimal decentralized MAC scheme under a constraint on the probability of primary collisions.","PeriodicalId":388309,"journal":{"name":"2013 Tenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116044610","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}
