Energy Efficient Cost-Aware Secure Routing (CASER) Protocol Design for Wireless Sensor Networks

Abstract

Lifetime optimization and security are two conflicting design issues for multi-hop wireless sensor networks (WSNs) In this paper, I first propose a novel secure and efficient Cost-Aware SEcure Routing (CASER) protocol to address these two conflicting issues through two adjustable parameters: energy balance control (EBC) and probabilistic-based random walking .Then determine that the energy consumption is severely disproportional to the uniform energy deployment for the given network topology, which greatly reduces the lifetime of the sensor networks. To solve this problem, I propose an efficient non-uniform energy deployment strategy to optimize the lifetime and message delivery ratio under the same energy resource and security requirement. Also provide a quantitative security analysis on the proposed routing protocol. For the non-uniform energy deployment, our analysis shows that I can increase the lifetime and the total number of messages that can be delivered under the same hypothesis. And also propose sleep awake state algorithms for achieve a high message delivery ratio while preventing routing blocking attacks.
