In this paper, the authors develop an analytical and simulation framework for Energy Efficient Secure Authenticated Routing Protocol (EESARP) for Mobile Ad-hoc NETworks. Their protocol provides efficient security against route discovery attacks using hop-by-hop signatures. It quickly detects the malicious nodes, thus assisting the nodes to drop the invalid packets, earlier. It also uses an efficient node selection mechanism which maximizes network life time and minimizes delay. It supports the node to drop the invalid packets earlier by detecting the malicious nodes quickly by verifying the digital signatures of all the intermediate nodes. A mathematical model is designed to estimate the packet delivery ratio in the network which is estimated using the probability of binomial distribution.
