Mobile Ad hoc Network (MANET) are self created and self organized by a collection of mobile nodes Heterogeneous mobile ad hoc network consists of devices with heterogeneous characteristics in terms of transmission power, energy, and capacity. Large transmission range of the high power nodes leads to interference in the network which reduces the spatial utilization of the resources. Clustering scheme is used here where cluster head node will play the role of transmitting packet from one cluster to the other. Election of a Cluster Head (CH) within a local cluster structure is very important in setting up relatively stable cluster structure. But the problem is that the cluster head selection is based upon only shortest path Due to this strategy, the cluster head selection algorithm is not much effective. Hence the proposed algorithm for the cluster head selection includes the parameters such as battery power, transmission range, hop count and time to live(TTL) which can increase the throughput and channel space utilization of the network.
