Reliable Random Key Pre-Distribution Schemes for Wireless Sensor Networks

Abstract

Abstract-The development of small-size, low-cost, and low-power sensors that possess sensing, signal processing and wireless communication capabilities is becoming popular for the wireless sensor networks. Cluster-based routing protocol is a good choice to achieve the energy efficiency for the wireless sensor networks. Due to the limited resources and energy constraints, complex security algorithms cannot be employed in sensor networks. In this paper, we propose a cluster-based routing protocol with a key pre-distribution scheme which improves the resilience of the network. In addition, our scheme is suitable for link error-prone environments. We describe the details of the algorithm and compare it with other schemes. Simulation results show that the proposed scheme achieves better performance in terms of security, efficiency and key connectivity.Index Terms-Cluster, key pre-distribution, security, wireless sensor networks.
