S-SurF: An enhanced secure bulk data dissemination in wireless sensor networks

Abstract

Wireless sensor networks (WSNs) have recently gained a lot of attentions as a hot topic of research, with extensive applications being explored. In WSNs, bulk data dissemination protocols are responsible for reprogramming, which have been proposed for efficiency and security. However, few of them can simultaneously achieve both reliability and security. To address this problem, we propose an enhanced protocol entitled Secure Survival of the Fittest (S-SurF) based on SurF [6] in this paper. The proposed protocol is composed of four main phases: packet preprocessing, flooding, negotiation and data verification. Moreover, S-SurF incorporates a time-reliability model to predict the minimum completion time and hence seizes the most opportune moment to transit between flooding and negotiation schemes. In addition, extensive analysis proves the efficiency and security of S-SurF.
