—In wireless sensor networks, an energy-efficient routing protocol is a key design factor to prolong network lifetime. Recently, Optimal Coverage-Preserving Scheme (OCoPS) is proposed in [11] as an extension of the Low Energy Adap-tive Clustering Hierarchy (LEACH) routing protocol with the coverage-preserving scheme which saves energy consumption through(More)
