CAMP: Congestion Avoidance and Mitigation Protocol for Wireless Body Area Networks

Advances in wireless communication technologies invented body sensor networks (BSNs) for health care systems. BSN monitors patients' health remotely and automatically. It is economical and helpful solution for both patients and healthcare providers. BSN is made up of small Bio-medical sensors (BMSs) and Body Coordinator (BC). BMSs sense and transmit data continuously. As BSN consist of many BMSs, the simultaneous data transmission results in congestion in the network. Congestion causes packet drops which attempt to be retransmitted again and again. Therefore, the BMSs drain their energy fast and consequently reduce the network lifetime. In this work, a congestion avoidance and mitigation protocol (CAMP) is proposed for BSNs. The experimental results shows that the proposed protocol carried out better results in terms of energy efficiency and network lifetime in BSNs.
