Lifetime Maximisation of Multihop WSN Using Cluster-Based Cooperative MIMO Scheme

J. Vidhya and P. Dananjayan

Abstract—Wireless sensor network (WSN) requires robust and energy efficient communication protocols to minimise the energy consumption as much as possible. However, the lifetime of sensor network reduces due to the adverse impacts caused by radio irregularity and fading in multihop WSN. A cluster-based cooperative multi-input and multi-output (MIMO) scheme is proposed as a solution for this problem. The proposed scheme extends low energy adaptive clustering hierarchy (LEACH) protocol and enables multihop transmissions among the clusters by incorporating cooperative MIMO scheme through the selection of cooperative sending and receiving nodes. The performance of the proposed MIMO system is evaluated interms of energy efficiency and reliability. Simulation results show that tremendous energy savings can be achieved by adopting cooperative MIMO scheme among the clusters. The proposed cooperative MIMO scheme prolongs the network lifetime with 75% of nodes remaining alive when compared to LEACH protocol.
