Title: A new LEACH-based routing protocol for energy optimization in wireless sensor network
Abstract: Due to lack of power source, energy is the key concern area in Wireless Sensor Networks. Maximum energy is used in transmission of data. Many research works have been done to develop routing algorithms to increase the lifetime of a sensor network. Among them clustering based approach is well known for achieving energy efficiency. This paper proposes a new routing strategy based on hierarchical routing protocol LEACH where clusters are refreshed periodically based on residual energy and distance. Reclustering distributes the workload among different nodes and in turn enhances the network lifetime by rotating the cluster head. The sensor nodes remain in active state only during its transmission slot. Rest of the time it remains in sleep state to save energy. LEACH, MOD-LEACH and the proposed protocol are simulated in MATLAB. The result shows that our proposed algorithm performs better than the LEACH and also MOD-LEACH protocol in terms of network lifetime. The proposed algorithm also gives more throughput than LEACH.
