Energy efficient routing is an important aspect of Wireless Sensor Networks for prolonging the lifetime of battery powered energy constrained nodes. Heterogeneities in node's energy, computation, and link have been considered in the area. However, the effect of traffic generation rate, which may be different for different nodes in heterogeneous WSN, is not well considered. In this paper, we have considered traffic heterogeneity, and analyzed its effect on well known hierarchical clustering based routing algorithm in the area. Also, we have proposed an improved cluster head selection mechanism under the traffic heterogeneous scenario. The approach can enhance the performance of existing commercial algorithms, and it could be an important aspect while developing new routing algorithms for heterogeneous WSN scenarios.
