基于优先级的无线体域网MAC协议研究

Research on MAC Protocol for Wireless Body Area Network Based on the Priority

由于体域网节点能量有限,不易更换,因此降低节点能耗,对延长节点和网络生存期十分重要。针对体域网在医疗领域应用的特点,根据数据业务类型和数据量的大小,采用设置优先级的策略,提高节点发包成功率,降低碰撞,以达到减少网络整体时延,降低节点能耗的目的。

Due to the limited node energy and which is not easy to replace, it is so important to reduce node energy consumption and prolong the lifetime of the network nodes. The data type and amount of data size is significant different in medical applications. It is a good strategy that we set priorities to improve the success rate and reduce collisions to save energy consumption.
