PROJECT TITLE :

Cost-Aware SEcure Routing (CASER) Protocol Design for Wireless Sensor Networks

ABSTRACT:

Lifetime optimization and security are 2 conflicting design problems for multi-hop wireless sensor networks (WSNs) with non-replenishable energy resources. During this paper, we tend to 1st propose a completely unique secure and economical Cost-Aware SEcure Routing (CASER) protocol to address these 2 conflicting issues through two adjustable parameters: energy balance control (EBC) and probabilistic-based mostly random walking. We have a tendency to then discover 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 downside, we propose an economical non-uniform energy deployment strategy to optimize the lifetime and message delivery ratio beneath the same energy resource and security requirement. We conjointly provide a quantitative security analysis on the proposed routing protocol. Our theoretical analysis and OPNET simulation results demonstrate that the proposed CASER protocol will offer an wonderful tradeoff between routing potency and energy balance, and can considerably extend the lifetime of the sensor networks in all scenarios. For the non-uniform energy deployment, our analysis shows that we can increase the lifetime and the full range of messages which will be delivered by more than four times under the identical assumption. We tend to additionally demonstrate that the proposed CASER protocol can achieve a high message delivery ratio whereas preventing routing traceback attacks.
