Energy-efficient multilayer routing protocol for SPMIPv6-based IP-WSN

摘要

Conservation of energy is considered the most critical issue for battery-powered IP-based wireless sensor networks (IP-WSN). IP-WSNs are of tremendous importance due to their broad range of commercial applications in healthcare, environmental analysis and precision agriculture. In these applications, global addressing and multilayer routing for IP-WSN are challenging issues. Most of the routing protocols in WSNs are layer-two based. For energy efficiency and end-to-end communication, the necessity of multilayer routing has been drawing significant attention. With the help of the sensor proxy mobile IPv6 (SPMIPv6) protocol, a tiny sensor node is capable of handling multilayer routing. In this paper, we discuss an energy-efficient multilayer routing protocol (EMRIP) for an SPMIPv6-based global IP-WSN scheme. Mathematical analysis and simulation results show that the proposed routing scheme significantly enhances the energy efficiency, throughput, minimises end-to-end delay, controls packet overhead and reduces mobility costs.
