【摘要】 针对无线传感器网络的节能特性和网络应用对服务质量(QoS)要求的不断提高,提出了一种节能高效的服务质量管理机制,运用Agent技术实现传感器节点的信息采集和QoS预约,当网络环境变化时进行QoS协商与再协商。与传统QoS机制相比,基于Agent实现的QoS管理机制能够最大限度对支持网络应用,更适合传感器网络的节能要求,延长网络的生命期。更多还原

【Abstract】 In this paper,we develop an energy-efficient QoS mechanism for wireless sensor networks using a agent-based model. In this model,agent is used for information collecting and QoS reservation at sensor nodes and executing QoS negotiation and renegotiation when network environment changes.Compared to traditional QoS Mechanisms,the agent based model will support applications to the greatest extent,and the lifetime of network is prolonged at the same time.更多还原
