SEECH: Scalable Energy Efficient Clustering Hierarchy Protocol in Wireless Sensor Networks

摘要: The energy efficiency is an important issue for employ distributed wireless sensor networks in smart space and extreme environments. cluster-based communication protocols play a considerable role saving hierarchical networks. In most of traditional clustering algorithms, cluster head (CH) simultaneously serves as relay node to transmit its cluster/other clusters data packet(s) the sink. As result, each would have CH many during network lifetime. our view, this inefficient from perspective because lots cases, due position comparatively more proper work and/a relay. This paper proposes new algorithm named scalable efficient hierarchy (SEECH), which selects CHs relays separately based on nodes eligibilities. way, high low degree are, respectively, employed relays. only few past researches, are different, but their goal was mainly mitigation burden intrinsically satisfied by proposed mechanism. To consider uniformity balance clusters, SEECH uses distance-based algorithm. Comparisons with LEACH TCAC show obvious better performance term evaluate scalability strategy, simulations conducted three different size scenarios.
