摘要
如何在大规模的移动自组网络中快速地找到所需的资源是一个迫切需要解决的问题。提出了一种称为EAQOS(Energy Aware QoS)的资源发现协议,本协议将资源查询请求过程同路由协议紧密结合,通过合并资源请求、QoS探测以及路径请求信息能够快速定位网络中的最优QoS的资源供应者并进行访问,同时有效降低了网络中的通信量以及能量消耗。最后通过NS2进行模拟实验,与两种不同的Qos资源发现协议相比,结果表明所提出协议的性能,包括查询延迟、通信代价以及能量消耗都有显著的提高。
How to locate the resource provider （RP） with the best QoS becomes a problem need to be solved. A resource discovery protocol called EAQOS resource discovery protocol is proposed in this paper, which combines the resource discover process tighdy with the muting protocol. With the combination of resource request message, QoS probes messages and mutes request messages, we could locate and access the RP quickly, at the same time, the communication cost and energy cost are kept as at a low level. Simulating this protocol using NS2, and the result indicates the performance of the protocol proposed by this paper is much better than the two protocols compared in query latency, communication cost and energy cost.
