ABSTRACT
The nodes in the mobile ad hoc networks act as router and host, the routing protocol is the primary issue and has to be
supported before any applications can be deployed for mobile ad hoc networks. In recent many research protocols are
proposed for finding an efficient route between the nodes. But most of the protocol’s that uses conventional techniques
in routing; CBRP is a routing protocol that has a hierarchical-based design. This protocol divides the network area into
several smaller areas called cluster. We propose a fuz zy logic based cluster head election using energy concept for
cluster head routing protocol in MANET’S. Selecting an appropriate cluster head can save power for the whole mobile
ad hoc network. Generally, Cluster Head election for mobile ad hoc network is based on the distance to the centroid of
a cluster, and the closest one is elected as the cluster head'; or pick a node with the maximum battery capacity as the
cluster head. In this paper, we present a cluster head election scheme using fuzzy logic system (FLS) for mobile ad hoc
networks. Three descriptors are used: distance of a node to the cluster centroid, its remaining battery capacity, and its
degree of mobility. The linguistic knowledge of cluster head election based on these three descriptors is obtained from
a group of network experts. 27 FLS rules are set up based on the linguistic knowledge. The output of the FLS provides
a cluster head possibility, and node with the highest possibility is elected as the cluster head. The performance of fuzzy
cluster head selection is evaluated using simulation, and is compared to LEACH protocol with out fuzzy cluster head
election procedures and showed the proposed work is efficient than the previous one.
