Evaluation of a Link Layer Secure Protocols for WSNs

Abstract

Communication energy is the main source of energy consumption for WSNs. all encryption protocols proposed for WSNs in the literature aim to reduce the security-related communication overhead in different ways to save communication energy. In other words, all proposed energy-efficient protocols affect security strength factors. However, ensuring communications security in WSNs indeed is critical. WSNs suffer from limited bandwidth, memory, and processing capabilities. They operate on the unattended mode in hostile environments. Therefore, an energy-efficient link-layer security framework is necessitated. In this paper; most link-layer security protocols are evaluated in terms of network lifetime and the end to end delay.
