Hopping sensor relocation in rugged terrains

摘要: Hopping sensors are a type of low cost mobile that small in size, have limited capability and imprecise movement. However, their unique method movement makes them suitable for rugged terrains. Sensors may fail when deployed terrain or an obstacle-abundant environment. Therefore, redundant be identified relocated to the sensor holes. This paper addresses problem relocating such capability-constrained obstructive We propose enhanced Quorum-Grid solution with Binary Splitting Message Forwarding (BSMF), which is decentralized can detect both existing newly appearing obstructions supplier consumer cells matching process. Furthermore, grid-based model introduced hopping sensors. Simulation shows our scheme significantly reduces communication overhead achieves relatively constant total energy consumption varying amount obstructions.
