一种高效节能的无线体域网MAC层协议
A Highly-efficient Energy-saving Wireless Body Area Network MAC Protocol
摘要
Abstract
With the rapid development of wireless sensor network technology,wearable and implantable biosensor technology,wearable and implantable wireless equipment can be used for remote monitoring signs information. To link the nodes and equipment which are atta-ched with person skin,implanted in person and surround people,wireless body area network arises at the historic moment. In WBAN, MAC protocol is responsible of conflict detection and processing,priority control,timeslot assignment,transmission order etc. So the de-sign of MAC protocol plays an important role in the reliability and efficiency of WBAN. In this paper,propose a high efficiency and ener-gy-saving MAC protocol (HE-MAC),which is based on IEEE 802. 15. 6. The protocol adopts dynamic priority control,dynamic time-slot allocation mechanism,dynamic proportion allocation mechanism of different access period length to achieve reliable transmission in the situation of low latency and low power consumption. By using the OMNet++ simulation platform,evaluate the network performance of AD-MAC protocol,IEEE 802. 15. 6 MAC protocol and CA-MAC protocol. The result of simulation shows that the proposed MAC protocol is superior to IEEE 802. 15. 6 MAC and CA-MAC in terms of throughput,power consumption and time delay.关键词
