Analysis of network performance by varying bs location in heterogeneous wireless sensor networks

The past few years have witnessed increased interest in the potential use of wireless sensor networks (WSNs) in applications such as disaster management, combat field reconnaissance, border protection and security surveillance. Sensors in these applications are expected to be remotely deployed in large numbers and to operate autonomously in unattended environments. To support scalability, nodes are often grouped into disjoint and mostly non-overlapping clusters. In this paper, we present a routing scheme based on the clustering of nodes for a heterogeneous environment such that nodes are having different energy levels but each node is capable of transmitting data to BS.
