Abstract-An energy efficient routing protocol is the major concern infield of wireless sensor network. In this survey paper we present some energy efficient hierarchal routing protocols, developed from conventional LEACH routing protocol. Main focus of our study is how these extended routing protocols work in order to increase the life time and how quality routing protocol is improved for the wireless sensor network. Furthermore this paper also highlights some of the issues faced by LEACH and also explains how these issues are tackled by extended versions of LEACH. We compare the features and performance issues of each hierarchal routing protocol.
Aslam et al. REF presented energy efficient hierarchical routing protocols developed from the conventional LEACH routing protocol to increase lifetime.
