Sink repositioning for enhanced performance in wireless sensor networks

摘要: Most of the energy aware routing approaches for unattended wireless sensor networks pursue multi-hop paths in order to minimize total transmission power. Since almost all data are routed towards a single sink (gateway), hops close that become heavily involved packet forwarding and thus their batteries get depleted rather quickly. In addition, interest optimizing tends increase levels relaying makes queuing delay an issue, especially real-time traffic. this paper we investigate potential gateway repositioning enhanced network performance terms energy, throughput. We address issues related when should be relocated, where it would moved how handle its motion without negative effect on present two factor traffic pattern determining new location optimized communication timeliness, respectively. The movement is carefully managed avoid losses. proposed validated simulated environment.
