Two-Tier Cluster Based Routing Protocol for Wireless Sensor Networks

Over the recent years, one of the most important problems in wireless sensor networks (WSNs) is to develope an energy-efficient and reliable routing protocol and provide network robustness. To achieve these objectives, we propose a new architecture for data dissemination 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.
