Co-CEStat: Cooperative Critical Data Transmission in Emergency in Static Wireless Body Area Network

Cooperative routing is a promising technique which exploits the broadcast nature of wireless medium to enhance network performance. Sensor nodes simultaneously transmit their data on different links and utilize cooperation between nodes. In this paper, a new protocol, Co-CEStat, Cooperative Critical data transmission in Emergency for Static Wireless Body Area Networks, is proposed. The protocol utilizes the merits of both direct and cooperative transmission to achieve higher stability period and end-to-end throughput with greater network lifetime. Simulations are conducted in MATLAB to compare the Co-CEStat´s performance with that of three other contemporary non-cooperative routing protocols.
