Abstract

In this paper, a reduction algorithm aiming at simplifying the topology of wireless sensor networks (WSNs) is proposed. First, we use simplicial complex as the tool to represent the topology of the WSNs. Then, we present a reduction algorithm which recurrently deletes redundant vertices and edges while keeping the homology of the network invariant. By reducing the number of simplexes, we make the simplicial complex graph nearly planar and easy for computation. Finally, the performance of the proposed scheme is investigated. Simulations under different node intensities are presented and the results indicate that the proposed algorithm performs well in reducing the number of simplexes under various situations.
