A topology control algorithm based on homology theory in software-defined sensor networks

In this paper, we propose a topology control algorithm based on homology theory for software-defined sensor networks (SDSNs). A tool from algebraic topology, Rips complex, is used to model the SDSNs. Then we try to switch off as many nodes as possible while preserving the coverage of SDSNs. Simulation results show that our algorithm can reduce more than 40% energy consumption.
