Mobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a Cluster Head Gateway (CHG) [1] [2]. As one of the most dominant factors in clustered Mobile wireless sensor networks, the selection of Cluster Head Gateway (CHG) can impact the network performance. The selection shall be subject to at least three factors. (i) The Transmission power of CHGs which should be more in order to cover large area and reduce the packet drops. (ii) The Mobility of CHGs should be low i.e. it has to stay in the existing network for longer time period to control and monitor other MANET nodes. AND (iii) The CHGs should provide better QoS to/than other MANET nodes within network. Now here the QoS deals with several parameters like Throughput, End-End Delay, Traffic Received, Traffic Sent and Storage Capacity (Queue/ Memory size) of CHGs. In this paper, we draw attention to propose Cluster Head Gateway Selection criteria approach. Firstly, we optimize the dynamic number of MANET nodes. Then we obtain the suitable CHGs out of the given MANET nodes via the improved selection procedures based on three selection phases mentioned above. Finally, this paper conducts simulation demonstrates the enhanced network performance.
