Wireless sensor network (WSN) is all time researched area as well as new concepts are introduced frequently. Here we will consider the hierarchical clustering routing protocol called LEACH and its variant as E-LEACH (energy leach). There may be a case in E-LEACH that selected cluster heads may be accumulated in certain specific area (or not distributed) due the consideration of only residual energy. Our proposed method includes the consideration of residual energy as well as selected cluster heads to be distributed in the entire wireless network. This balance load and increase the network life time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
