A Node Quality Based Cluster Header Selection Algorithm for Improving Security in MANET

Mobile Ad-hoc Network (MANET) is a significant type of wireless sensor networks, executes on a resource restricted environment. MANET turns into an emerging technology for its special features. Secured data transmissions in MANET can be established by dynamic Node clustering algorithm. Selecting an efficient Cluster Head (CH) node is a challenging issue in MANET due to finite battery power supply. Cluster generation is a precious task in terms of power distribution of nodes to the clusters. Every cluster having one or many selected cluster head(s), all cluster Heads (CH) nodes are interconnected to form a networks and broadcasting the data. The Cluster Head (CH) node is authorized node for scanning a node performance and other security related functions. A Cluster Heads should be capable of functioning under a limited energy mode and resource constraint environments, malicious nodes can drain energy rapidly and reduces the total lifespan of the networks. In this paper proposed an efficient algorithm for selecting a Cluster Head (CH) nodes by using K means algorithm and Weighted clustering Algorithm (WCA).This algorithm aims to elect a node having high Sustainable Cell (SC) rate as a cluster Header (CH) A Sustainable Cell (SC) rate will be computed by all nodes individually based on the important quality of a node, for instance energy utilization, degree of a node, remaining energy, mobility of node and distance between the CH and base stations. The proposed method also implements an algorithm for removing malicious nodes from the network and increasing the MANET security. By using high sustainable cluster head, this proposed algorithm will improve the stability of a network and network throughput.
