Abstract: In order to decipher the packet loss in wireless Ad hoc networks，a packet loss model is drawed based on the fact that when the normalized throughput increasing the packet loss rate also increasing.Using this packet loss model，the throughput of wireless Ad hoc networks with chain-topology is explained，the result is same as the simulation by NS-2.

摘要： 针对无线Ad hoc网络中的丢包现象，假设网络中节点的丢包率是与归一化吞吐量有关的，并且在此假设的基础上提出一种分析丢包率的数学模型，利用这种模型可以一定程度的解释无线Ad hoc网络中的丢包。仿真结果表明利用该模型的理论分析结果与仿真结果具有相当的相似性，表明该模型在一定程度上解释了无线Ad hoc网络中的丢包问题。
