Abstract
Wireless network has significantly affected human life. MAC protocols which already existed mostly transmit data without priority so that emergency event data cannot be sent quickly to destination nodes. In this paper, a new protocol called priority-and-activity-based QoS MAC (PAQMAC) protocol is proposed, in which not only the priority of data in transmission is considered, but also the active time is dynamical adjusted by recording the activity degree in a duty cycle. With the priority classified, it provides enough time to deal with emergency event, thus the security and management of network are also improved. Simulation results show that PAQMAC protocol can reduce transmission delay and decrease energy consumption of network.
无线网络已经极大地影响了人类的生活。现有的MAC协议在传输数据时大多没有优先级，导致紧急事件数据无法快速发送到目的节点。本文提出了一种新的基于优先级和活动的QoS MAC (PAQMAC)协议，该协议不仅考虑传输数据的优先级，而且通过记录一个占空比内的活动程度来动态调整活动时间。通过对优先级进行分类，为应急事件的处理提供了充足的时间，从而提高了网络的安全性和管理性。仿真结果表明，PAQMAC协议可以减少传输延迟，降低网络能耗。
