Energy efficient realization of Clustering Patch routing protocol in wireless sensors network
P. K. Poonguzhali · 2012
Wireless sensor network (WSN) consists of tiny sensor nodes with sensing, computation and wireless communication capabilities. Now days, it is finding wide applicability and increasing deployment, as it enables reliable monitoring and analysis of environment. The design of routing protocols for WSN is influenced by many challenging factors like fault tolerance, energy efficiency, scalability, latency, power consumption and network topology. Due to the limited power of the wireless sensor networks (WSNs)[1], the network lifetime becomes a critical index in WSN's. Newly evaluative standard can depict the performance of WSN's more effectively. Meanwhile, a Clustering Patch Hierarchical Routing Protocol (CPHRP) is proposed with purposes of improving network coverage rate and effective network lifetime in WSN's. In this paper, we reveal the shortcomings of currently evaluative standard and the current cluster-based routing protocol by HEED. Under the newly evaluative standard, CPHRP can guarantee more than 90% network coverage rate within most of network lifetime [5] when the number of inner-cluster sense nodes is above 6. With the multiple growth of network nodes, the effective network lifetime of CPHRP rises by more than 60%. When the number of inner-cluster nodes increases in multiple of 6, the growth of its network lifecycle is more than 50% in contrast of the less than 7% of HEED.
