Secure and energy-efficient routing for cluster-based wireless sensor networks

Abstract

Security is a prime concern in the resource constrained wireless sensor networks. Traditional cryptographic mechanisms cannot be used with these networks due to their limited battery. Clustering is one of the popular methods to improve the energy efficiency of WSN. In this chapter, the authors propose a secure routing protocol for cluster-based wireless sensor networks. A hierarchical topology is formed by the base station, which is also responsible for distributing the cryptographic keys among the nodes. Security analysis of the proposed protocol is done against various security attacks. The efficiency of the proposed protocol is explained through mathematical calculations and simulations. The proposed protocol also performs better than other existing secure protocols for cluster-based WSN regarding battery life and security overhead. © 2018, IGI Global. All rights reserved.
