摘要： Ad Hoc网络通过节点的中继实现通信，无须基础设施的支持，在军事、医疗、科研等方面有广泛的应用前景。该文使用OPNET仿真了在均匀分布、随机分布拓扑结构下节点高速移动的网络状态，以重传次数为度量，比较了流量、能量有限性对Ad Hoc网络能量性能的影响。结果表明流量、能量的有限性对Ad Hoc网络能耗具有不同的影响特性。

Abstract: Ad Hoc network, which can gain wide application in military, disaster relief and research fields, can work by relaying packets through intermediate nodes without the support of fixed infrastructure. Different scenarios in evenly-distributed and random-distributed topology in high-speed mobile ad hoc networks(MANET)are simulated through OPNET. Results based on retransmission times show that both flow and energy constraints can affect energy dissipation but their effects are different.

Key words: Ad Hoc, flow, energy constraints, retransmission times
