An Energy Efficient and Reliable Two Tier Routing Protocol for Topology Control in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) is used in many applications for precise monitoring. The key issue in WSNs is energy conservation is the most important strategies to save energy and to prolong the lifetime of the WSNs are topology control. A reliable energy-efficient topology control protocol in wireless sensor networks is proposed, it is one of the most important techniques utilized to reduce energy consumption in wireless sensor networks, considers the residual energy and number of neighbors of each node for cluster formation, and well-balanced a loss of energy of the network. Topology control is an efficiency method that can extend the network lifetime in a wireless sensor network. Cluster heads selection and selected cluster head maintains connectivity and network coverage with respect to time in this approach. Balancing energy consumption and prolonging network lifetime are open challenges in Wireless Sensor Networks. This not only balances the energy consumption of each node and provides prolonged the network life time but also provides global reliability for the whole network.
