Abstract

The low power wireless sensor networks need both security and efficiency to collect sensitive data from various nodes.. Data fusion nodes fuse the collected data from nearby sensor nodes before they sent to the base station. If a fusion node is compromised, then the base station cannot ensure the correctness of the fusion data. Several methods are proposed, that deal with providing an assured data transfer to the base Station. In this paper, a novel power-efficient data fusion assurance scheme has been proposed using silent negative voting mechanism. The proposed scheme has been compared with witness based fusion assurance scheme as well as the direct voting based fusion assurance scheme. The proposed scheme has produced very good impact with better power efficiency and lower network overhead.
