The studyof the behaviour of different nodes is a remarkable achievement in the wireless sensor networks. Wireless sensor network are hierarchical clustered. Cluster based routing protocols are proven to be energy efficient when compared to other routing protocols. Most of the cluster based routing protocols, especially low energy adaptive clustering hierarchy (LEACH) protocol, follows dynamic, distributed and randomized (DDR) algorithm for clustering. Since there is a lot of randomness present in the cluster process, number of cluster heads generated varies highly from the optimal count. An overview to design a better variant of LEACH MAC protocols for heterogeneous network is proposed in this paper. The proposed study introduces the time synchronization in sending packets and optimal data aggregation table.
