Due to congenital restriction of sensors, it is always a crucial issue on how to utilize limited energy effectively. We first put forward a network topology construction method, based on energy saving, including the way of forming a cluster and selecting middle heads and cluster heads. We then employed Simulated Annealing method to optimize energy consumption of the whole system. Results show t...

This paper presents an adaptive concentric clustering scheme to construct a routing topology which can reduce the transmission distance between nodes in a wireless sensor network for gathering sensory data from a base station. Depending on the current location of base station, the proposed algorithm can divide the set of network nodes into several concentric clusters and establish individual ro...

Routing in MANET is different from routing in wired network. One way to reduce routing overhead is to divide the network into clusters. Clustering of nodes into groups efficiently minimizes routing traffic overhead. Several algorithms have been proposed by researchers for formation of clusters and election of cluster heads. Most of the algorithms consider only one performance factor such as nod...

Inside clusters,...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption.
