1、上海交通大学硕士学位论文无线传感器网络协议的QoS问题研究姓名:王涛申请学位级别:硕士专业:控制理论与控制工程指导教师:张卫东20060101(MAC)子层QoS协议,详细地分析了MAC协议的QoS支持机制,并且具体分析了四种无线传感器网络MAC协议对QoS的支持。接下来重点研究了无线传感器网络支持QoS路由的网络层协议,讨论了路由协议的QoS支持机制,详细分析了两种无线传感器网络QoS路由协议:ReInForM协议和SPEED协议。最后研究了无线传感器网络所特有的能量约束问题,通过研究基于能量约束的路由算法和相关QoS路由
2、算法,本文提出了基于SPEED协议的一种能量约束QoS路由改进算法。针对SPEED路由协议缺乏对无线传感器网络能量受限特点的考虑,采用将能量约束路由算法和SPEED协议的SNGF算法进行结合,改进了SPEED协议对无线传感器网络能量特性的支持。因此在结合无线传感器网络自身能量受限的特点下,具体研究无线传感器网络各层的QoS相关协议,是今后无线传感器网络协议研究中的一个非常重要和有意义的研究方向。关键词:无线传感器网络(WSNs),服务质量(QoS),能量(Energy),路由协议(RoutingProtocol),媒体访问控
