TWO TIER CLUSTER BASED ROUTING PROTOCOL (TTCRP) FOR WIRELESS SENSOR NETWORKS

Abstract

Wireless Sensor Networks (WSNs) consist of thousands of small nodes having the capability of sensing, computation, and wireless communication. Many routing, power management and data dissemination protocols have been particularly designed for WSNs where energy utilization is an essential design issue. Since wireless sensor network protocols are application specific, therefore the focus has been given to the routing protocols that might be different depending on the application and network architecture. Over the recent years, one of the most important problems in wireless sensor networks (WSNs) is to develop an energy-efficient and reliable routing protocol and provide network robustness. To achieve these objectives, we propose a new data dissemination protocol called Two Tier Cluster Based Routing Protocol (TTCRP) for reliable data delivery in WSNs. TTCRP uses resource rich cluster heads with dual channels to form the clusters for efficient data delivery. While it provides power control algorithm to connect the isolated low power sensor nodes with minimum required power that achieves the network robustness. Simulation results reveal that TTCRP is efficient and provides reliability in both uniform as well as non-uniform sensor nodes deployment
