Clustering is an effective approach for organizing the network into a connected hierarchy, load balancing, and prolonging network lifetime. Clustering protocols in wireless sensor networks are classified into static and dynamic. In static clustering, clusters are formed once, forever and role of the cluster head is scheduled among the nodes in a cluster. However, in dynamic clustering the time is...
Clustering sensor nodes is an effective topology control for increasing network lifetime and scalability. It also, balances the load on the sensor nodes. HEED is a well known distributed clustering protocol that uses both energy and communication cost to elect Cluster Heads (CHs) in a probabilistic way. This paper improves HEED protocol using fuzzy logic and a non probabilistic approach for CH election...
There are two kinds of data collection in wireless sensor network: passive and active. We here propose an adaptive, energy-efficient clustering protocol (AEEC) which is applicable to both passive and active data collection. The proposed protocol selects cluster heads according to the rank of node remaining energy and the number of node neighbors. Unlike traditional clustering protocols, it is an adaptive...
