Performance Degradation of Heterogeneous Wireless Sensor Network in the Presence of Non Cooperative Nodes

Recently Wireless Sensor Networks (WSN) has gained research interest for remote area monitoring and tracking in unattended environments. WSN may be heterogeneous to provide resources and aggregation of resources will be helpful for efficient distributed computing. Sensor nodes in WSN are used to collect application specific data, perform some pre computing and send the computed values to sink nodes or base station where the application resides. Usually message sending is done by multi hop forwarding. Since each node is battery powered, the major goal of WSN is to maximize the battery life time. Among the different types of routing methods cluster based routing is the best one for energy conservation.
