Efficient movement control actor relocation for honing connected coverage in wireless sensor and actor networks

摘要: Recently, Wireless sensor and actor networks (WSANs) are getting growing interest from research community because of their potential for enormous range applications. Actors in WSANs capable to perform application-oriented actions response detected events such as extinguish fire rescue survivors. To actions, efficient placement is extremely crucial the actors cover area interest. Moreover, maintaining strong inter-actor connectivity desirable interact with each other synchronize operation. However, most application environments inaccessible due harsh terrain; therefore random deployment nodes becomes an inherent choice. Random often strangles coverage leads high concentration deployment. Therefore, it imperative pursue autonomous dispersion. The prime objective this work improve connected while minimizing movement overhead. This paper presents a localized distributed Movement Control Actor Relocation (MCAR) algorithm. MCAR pursues post-deployment repositioning way that repel better staying connected. Simulation results validate performance proposed scheme terms resource efficiency. show can reduce distance up 32% improving 29% compared contemporary schemes.
