Abstract

In this paper, we design a medium access control (MAC) layer prootocol for wireless body area networks (WBANs) to cope with inter-WBAN interference. Each WBAN consists of a coordinator and multiple sensor nodes. Interference happens when multiple nodes transmit to their coordinators at the same time. To avoid interference among WBANs, carrier sensing multiple access with collision avoidance (CSMA/CA) is implemented at the coordinator level; while for communications within each WBAN, the coordinator uses beacon messages to centrally arrange all the transmissions to avoid collisions. In the proposed protocol, the coordinator adaptively adjusts its frame length based on its perceived interference level. By doing so, a WBAN can enjoy a high throughput under a light interference level, while giving other WBANs a fair share of channel access chance when the number of surrounding WBANs is large. We further design a sensing scheme to reduce the sensing power consumption for the sensor nodes and discuss how to extend the protocol for multi-channel and QoS support. Finally the simulation results verify the effectiveness of the proposed protocol.
自适应CSMA/CA MAC协议减少无线体域网络间wban干扰
本文设计了一种无线体域网络(wban)的介质访问控制(MAC)层协议,以应对无线体域网络间的干扰。每个WBAN由一个协调器和多个传感器节点组成。当多个节点同时向它们的协调器发送信号时,就会产生干扰。为了避免wban之间的干扰,在协调器级实现了载波感知避碰多址(CSMA/CA);而对于每个WBAN内的通信,协调器使用信标消息集中安排所有传输,以避免冲突。在该协议中,协调器根据感知到的干扰水平自适应调整帧长。通过这样做,WBAN可以在轻度干扰水平下享受高吞吐量,同时在周围WBAN数量很大时为其他WBAN提供公平的信道访问机会。我们进一步设计了一种传感方案,以降低传感器节点的传感功耗,并讨论了如何扩展协议以支持多通道和QoS。仿真结果验证了该协议的有效性。
