一种改进的无线体域网MAC协议
An Improved MAC Protocol for Wireless Body Area Network
摘要
Abstract
In recent years,along with continuous innovation of the sensor technology and communications technology,Wireless Body Area Network (WBAN) plays an important role in healthcare field.The characteristics of WBAN is different from Wireless Sensor Network (WSN),and each sensor of it has a unique purpose.WBAN has great potential and prospects in remote diagnostics,special populations monitoring and community medical care.However,WBAN is battery-powered,energy of which is limited,and computing and storage,wireless communications capabilities are not high,especially for embedded nodes do not frequent replacement of batteries.In view of heterogeneousness of data types for WBAN,by analyzing the IEEE802.15.4 wireless personal area network standard,a new MAC Protocol based on slotted ALOHA is designed.It can distinguish in emergency situations to ensure the priority transmission of emergency operations.The performance is analyzed with simulation,and the results show that compared with existing MAC Protocol,it has significant improvement in the energy consumption,number of packets,throughput and so on.关键词
