Energy and Memory Efficient Clone Detection with Multiple Witness Headers

Abstract

Wireless sensor networks [WSNs] have become very popular and ubiquitous technologies for everyday applications. WSNs are vulnerable to clone node attacks that effects in many devastating ways. An attacker can capture a sensor node to install number of clone nodes with same privacy information causing serious security threats and deterioration in network lifetime. Current security scheme along with distinct advantages suffer from number of limitations. A good counter attacks measure should not only cater for security and energy-efficiency but network lifetime as well. Most of the previous works aim at maximizing the clone detection probability without considering the impact of proposed clone detection protocol on the network lifetime and required data buffer storage. Hence we carefully design a distributed clone detection protocol with random witness selection by jointly considering the clone detection probability, network lifetime and data buffer capacity.
