基于Geom/G/1模型的Ad Hoc网络节点性能分析 Performance Analysis of Ad Hoc Network Node Based on Geom/G/1 Model

本文将网络中的每一个节点看作一个排队系统，基于Geom/G/1排队模型给出了缓存器中排队分组的平均队长，并利用Little定理得到分组的等待时延。通过计算发送一个分组的平均开销，进而得到了信道的平均利用率的计算方法，并将该方法应用到Ad Hoc网络中，得到了Ad Hoc网络的开销和信道利用率。 In this paper, we consider each node in the network as a queuing system. Based on the Geom/G/1 queuing model, we give the average queue length in the buffer of node, and use the Little theorem to get the waiting delay of the packet. By calculating the average overhead of sending a packet, the method of calculating the average utilization of the channel is obtained, and which is applied to obtain the overhead and channel utilization of the Ad Hoc network.
