A reliable transmission scheme for security and protection system based on internet of things

A reliable transmission scheme for security and protection system (SPS) based on internet of things is proposed. A cooperative transmission mechanism is designed to improve the reliability and efficiency of data services. Meanwhile, rate selection algorithm based on channel conditions is elaborated. An analytical model is introduced to evaluate performance of our proposed cooperative broadcast scheme. Simulation results indicate that the proposed scheme can significantly improve throughput performance compared to conventional scheme.
