DMED: A Dual-Mode Energy-Driven Routing Protocol for Wireless Planetary Exploration Sensor Network

摘要

Energy-efficient is a challenging issue in Wireless Sensor Network, which is a promising technology being widely used in the planetary exploration. Considering the rechargeable solar batteries equipped in the planetary surface sensor system, this paper presents a novel and special dual-mode energy-driven (DMED) routing protocol for the planetary exploration. According to the charging and sleeping states of the solar battery, the dual modes (i.e. day mode and night mode) of the node are obtained. Differential theory is adopted in the DMED weighted average of reciprocals consultation mechanism to choose the optimal value of p which can be adjusted dynamically under dual modes. The experimental results indicate that DMED is superior to ad hoc on-demand distance vector in the performance of energy balancing, and it prolongs the network lifetime effectively. The research of this work is benefit to the planetary exploration, and the research results provide reference value to the special routing protocol design.
