Routing Algorithm for Delay Tolerance in Wireless Sensor Networks

Cong Li, Shujuan Dong


In a regular sensor node, there are three activities that are the core sources of energy consumption i.e. sensing, computation, and radio operations. Multi-Group, a novel routing algorithm based on LEACH (MG-LEACH) that has been utilized in redundant deployed sensor nodes to improve the network lifetime is explored. It has been suppressing the correlated data gathered by the sensor nodes by monitoring the similar event, thus not only reducing the data transmission inside the clusters but also conserving the energy of deployed sensor nodes consequently to improve the overall network lifetime. The proposed routing algorithm has been simulated using MATLAB to verify the efficiency in enhancing network lifetime. A critical evaluation of routing algorithm is conducted to determine the relevance and applicability in increasing network lifetime. Simulation results demonstrated that it has performed better than LEACH and enhanced network lifetime by up to approximately 90%.
