Cost-Aware SEcure Routing (CASER) Protocol Design for Wireless Sensor Networks - 2015
Lifetime optimization and security are two conflicting design problems for multi-hop wireless sensor networks (WSNs) with non-replenishable energy resources. In this paper, we first propose a completely unique secure and economical Value-Aware SEcure Routing (CASER) protocol to address these two conflicting problems through two adjustable parameters: energy balance control (EBC) and probabilistic-based mostly random walking. We tend to then discover that the energy consumption is severely disproportional to the uniform energy deployment for the given network topology, that greatly reduces the lifetime of the sensor networks. To solve this problem, we have a tendency to propose an efficient non-uniform energy deployment strategy to optimize the lifetime and message delivery ratio underneath the identical energy resource and security requirement. We tend to additionally offer a quantitative security analysis on the proposed routing protocol. Our theoretical analysis and OPNET simulation results demonstrate that the proposed CASER protocol can provide an wonderful tradeoff between routing potency and energy balance, and can significantly extend the lifetime of the sensor networks in all situations. For the non-uniform energy deployment, our analysis shows that we can increase the lifetime and the full number of messages that can be delivered by a lot of than four times below the same assumption. We have a tendency to additionally demonstrate that the proposed CASER protocol can achieve a high message delivery ratio whereas preventing routing traceback attacks.
