Self Reconfigurable Clustering (Re-Clustering) mechanism is very useful and emerging technique whenever the cluster head failure occurs in the network due to limited battery power, low radio transmission range, minimum memory speed. The energy compulsion of each sensor node directly affects the scalability, efficiency and lifetime of a sensor network. In heterogeneous wireless sensor network, each node is having different amount of energy. This paper mainly focuses on Re-clustering in heterogeneous wireless sensor network for maintain the load balance and data aggregation .The proposed protocol mainly focus on the key parameters of the sensor nodes which are prolong the network lifetime such as average residual energy of the each cluster head in order to increase the network lifetime, energy dissipation of the sensor nodes.
