Abstract

Wireless sensor networks (WSNs) have become an interesting area to researchers in recent years due to the low
cost of sensor nodes, wide application areas and with low or no cost of maintenance after deployment in a target area. In
some sensor system applications, the nodes are hard to reach and it is impossible to replace their batteries. So the nodes
must operate without battery replacement for a long time. Such conditions make the system power consumption a very
crucial parameter. Thus, Clustering is an energy efficient way that divides sensor nodes into many clusters, each of
which has a cluster head. In this paper a new cluster-based routing algorithm for hierarchical WSNs has been proposed
to select an alternative node to get replaced in place of node which loses its energy such that it extends the lifetime of
entire network and avoids data loss. The simulation results show that, for large scale WSNs, our proposed algorithm
performs better than the typical existing routing algorithms in terms of network lifetime
