首发时间:2014-11-03
摘要:智能电网中数据业务的到达具有突发性的特点,传统的CSMA/CA MAC算法不能实现对高优先级业务的有效处理。为了实现高优先级业务在智能电网故障场景中低时延的要求,能更好地保证QoS参数,本文提出了基于资源预留的MAC算法,预留一部分带宽,通过对剩余带宽的合理分配来保证业务的时延值,以弥补传统的CSMA/CA机制在突发业务中的不足,通过NS2软件进行仿真实验,结果表明,在传统的MAC算法那中加入资源预留机制,能保证高优先级业务的QoS参数,并使低优先级业务时延也得到控制。

Resource Reservation Based adaptive smart grid MAC Algorithm
Abstract:In smart grid technologies,the arrival of data service cabins with the characteristics of burstiness,the traditional CSMA/CA MAC algorithm can not achieve the high priority service.In order to achieve the low time delay of the high priority service in the fault scenarios in smart grid and to ensure the QoS parameter,in this paper,resource reservation based MAC algorithm has been proposed,with reserving a part of the bandwidth,through the reasonable distribution of excess bandwidth,finally ensures the low time delay of service.This method can make up the deficiency of CSMA/CA in the bursty traffic.We can do the simulation experiments through NS2 soft.The experimental results showed that the QoS parameter of high priority servece is guaranteed,and the time delay of low priority service can be controlled in the traditional CSMA/CA with resource reservation based MAC algorithm.
