Analysis of Key Management Schemes in Dynamic Wireless Sensor Networks

Abstract

With the increasing use of sensor nodes in several stationary and mobile devices in today’s Internet-connected life, providing security is a challenging issue. Ensuring security in wireless sensor networks is a popular subject which has been studied for almost a decade on static networks. However, due to the new trend to use sensor nodes in mobile applications, considering dynamicity is important in providing secure communication between sensor nodes. In particular, providing efficient key management schemes for mobile networks, due to its potential limitations is essential. In this paper, we provide a survey on existing key management schemes proposed for dynamic wireless sensor networks. We also provide a comparison between these schemes in terms of different security and efficiency metrics.
