LEACH-CS:A Customizable Zone-spanned Multi-hop Routing Protocol in WSNs
Jinjing Tao · 2011
This paper,based on the existing LEACH routing algorithm,proposed a novel customizable zone-spanned multi-hop routing algorithm(LEACH-CS) for large-scale,energy limited wireless sensor networks.At first,we introduced the concept of zone.On this basis,an additional cluster-head may be elected on demand during cluster-head selection process.The purpose is to optimize multi-hop routing with the constraint of multi-zone distance threshold.Our simulation experiment demonstrated that,compared with the existing LEACH protocol,the LEACH-CS could reduce the energy consumption of the cluster-heads significantly and extend the life-cycle of large-scale networks due to more uniformly distributed dead nodes.
