A SUPERFRAME ADJUSTMENT AND SLOT RESERVATION-BASED MAC PROTOCOL FOR WIRELESS BODY AREA NETWORKS

Abstract: In recent years, health monitoring applications measuring a multitude of physiological parameters has been increased due to the evolution of the biomedical sensors. Since biomedical sensors in WBAN (wireless body area network) operate by batteries, high power efficiency is required due to the limited available energy. Furthermore, reliable data transmission is required to deliver urgent measured information to the sink node. In this paper, we present a superframe adjustment and slot reservation-based MAC protocol for wireless body area networks (WBANs) which we call H-MAC (health MAC) for health applications. In the H-MAC, senders can send a burst data when there is an urgent event such as heart beats. These events are usually critical, so the measured burst data should be transmitted in limited time to their final destination node. The H-MAC protocol reduces the packet transmission delay and prolongs the network lifetime in comparison to existing related MAC protocols. |
Keywords and phrases: WBAN, MAC, health monitoring, delay, energy.
