Modified Hex Based Routing In WSN

Wireless sensor network consists thousands of nodes with limited battery power. The sensing information must be obtained in an efficient manner for the long lifetime of sensor network. The base station collects the data from all nodes. Direct transmission of data from each node towards the base station consumes a lot of energy. To optimize the performance of network, nodes are arranged in the form of clusters. Each cluster contains a cluster head. Local nodes transmit data to cluster head and cluster head to the base station. The cluster head transfer data to base station in one hop. The performance depends upon selection of cluster head, cluster size as well as on the cluster shape. The proposed technique reduces the energy consumption hence enhance the network life. The existing protocol as well as the modified protocol is implemented using the MATLAB; and their performance is compared by varying the number of nodes.
