In this paper, the authors study the impact of heterogeneity of nodes in the zone conception of clustered wireless sensor networks. Most of the classical heterogeneous clustering protocols consider the sensing field as a whole for cluster formation. Unlike the existing protocols, the proposed protocol creates rectangular fields called zones and the number of cluster heads elected depends on the zone size and the number of nodes. The best way to extend the life span of sensor nodes is to reduce the complexity in communication costs between the sensor nodes and their cluster heads and compute optimal probability of nodes to become cluster heads in their respective zones.
