Weighted tree based routing and clustering protocol for WSN

In wireless sensor networks (WSN), clustering, a method of grouping sensor nodes, has numerous advantages. To ensure long-term operation of clustered WSN, two efficient routing protocols are proposed in this paper. The first is the Control Data Dissemination Protocol (CDDP) which forms a tree that connects all the nodes in the network, this tree will be used later to transfer control data to the base station. The second is a centralized weighted clustering protocol that uses the CDDP to transmit control data to the base station which will select the best cluster heads in the network according to a weighted criteria function. The effect of using a realistic energy consumption model in cluster-based communication for WSN will be investigated. The effectiveness of the proposed protocols are demonstrated by numerical simulations.
