Incremental Relay-Based Co-CEStat Protocol for Wireless Body Area Networks

This paper presents Incremental relay-based Co-CEStat protocol for Wireless Body Area Networks (InCo-CEStat). This protocol is proposed to enhance the performance of Cooperative Critical data transmission in Emergency for Static Wireless Body Area Networks (Co-CEStat) and Advanced Co-CEStat (ACo-CEStat). Proposed protocol utilizes the merits of both direct and cooperative transmission to achieve reliable and quick data delivery and greater network stability period. Incremental relay based cooperation is utilized to improve energy efficiency of the network. At relays, Detect-and-Forward (DF) technique is used, whereas, selection combining technique is utilized at sink. Simulation results are obtained in MATLAB in which proposed protocol is compared with ACo-CEStat and Co-CEStat protocols. Simulations show that InCo-CEStat has 37% and 58 % more stability period than ACo-CEStat and Co-CEStat. InCo-CEStat also achieved 51% and 79% higher throughput than that of compared protocols.
