Abstract

A number of tiny sensor nodes are strategically placed in and around the human body to obtain physiological information. The sensor nodes are connected to a coordinator or a data collector to form a WBAN. WBAN consists of variety of medical and non-medical applications with aggregate data rate requirement ranging from few bytes per second to 10Mbps. These applications are having relatively different energy saving, reliability and quality of service (QoS) requirements. The existing MAC protocols present in various short and medium range wireless technologies such as 802.11 and 802.15.4 have been designed for specific purposes, and therefore, do not fulfill the diverse performance requirements across all WBAN applications. In this paper, we propose a poll-based MAC protocol (PMAC) for WBAN, which can meet such a diversified functional requirements of various WBAN applications. In particular, we introduce few concepts in polling based channel access mechanism to make an energy efficient and QoS aware MAC protocol. The design has been validated by obtaining the performance of proposed PMAC protocol through simulation.

PMAC:一种基于轮询的无线体域网络MAC协议

许多微小的传感器节点被战略性地放置在人体内部和周围，以获取生理信息。传感器节点连接到协调器或数据采集器，形成WBAN。WBAN由各种医疗和非医疗应用组成，其聚合数据速率要求从每秒几个字节到10Mbps不等。这些应用具有相对不同的节能、可靠性和服务质量(QoS)要求。现有的MAC协议存在于各种短距离和中距离无线技术中，如802.11和802.15.4，它们是为特定目的而设计的，因此不能满足所有WBAN应用的各种性能要求。本文提出了一种基于轮询的WBAN MAC协议(PMAC)，以满足各种WBAN应用的多样化功能需求。特别地，我们在基于轮询的信道访问机制中引入了一些概念，以实现节能和QoS感知的MAC协议。通过仿真验证了所提出的PMAC协议的性能，验证了设计的正确性。
