Towards network lifetime maximization: sink mobility aware multihop scalable hybrid energy efficient protocols for Terrestrial WSNs

摘要: We propose two routing protocols for Terrestrial Wireless Sensor Networks (TWSNs): Hybrid Energy Efficient Reactive (HEER) and Multihop (MHEER) protocol. The main purpose of designing these is to improve the network lifetime particularly stability period underlying network. In MHEER, node with maximum energy in a region becomes cluster head (CH) that particular round (or cycle) time number CHs each remains same. Our techniques outperform well-known existing protocols: LEACH, TEEN, DEEC terms lifetime. also calculate confidence interval all our results which helps us visualize possible deviation graphs from mean value. implement sink mobility on HEER MHEER. refer them as HEER-SM MHEER-SM. Simulation show MHEER-SM yield better compared counterpart techniques. have carried out simulations 500 1000 nodes same field dimensions besides 100 nodes. Simulations prove proposed schemes behavior nodes; is, MHEER are scalable well.
