Survey on LEACH-based security protocols

Abstract

Energy efficiency is one of the major concerns in designing protocols for WSNs. One of the energy-efficient communication protocols for this network is LEACH that works on cluster-based homogeneous WSNs. Though LEACH is energy-efficient but it does not take security into account. Because WSNs are usually deployed in remote and hostile areas, security becomes a concern in designing a protocol. In this paper we present our security analysis of five security protocols that have been proposed to strengthen LEACH protocols. Those protocols are SLEACH, SecLEACH, SC-LEACH, Armor LEACH and MS-LEACH.
