摘要

在军事和民用应用中使用移动自组网(manet)有很大的兴趣。这些网络的容量和优化设计仍有许多有趣的问题有待研究。本文着眼于这些突出问题之一。具体来说,所解决的问题是确定如何通过以节能的方式优化放置额外的动态节点来增加MANET的容量。该节点被设想为一个平台,其主要目的是提高MANET的容量和功率效率。给定特定的网络结构,研究了附加节点的最优位置。在插入节点的同时,所有节点的功率调整都以与拓扑控制一致的方式进行。然后将此方法与不使用额外节点的拓扑控制方法进行比较。仿真结果表明,所述技术可以显著减少MANET内的干扰,从而提高网络容量。MANET的功耗下降也带来了额外的好处,从而增加了网络的运行寿命。从得到的结果可以推断,一个简单的分布式算法来寻找最优点不是一个微不足道的练习。

Power and Placement: Increasing Mobile Adhoc Network Capacity and Power Efficiency
There is great interest in using mobile adhoc networks (MANETs) for military and civilian applications. There are still a lot of interesting problems investigating the capacity and the optimal design of these networks. This paper looks at one of these outstanding problems. Specifically the problem addressed is to determine how the capacity of a MANET can be increased by the optimal placement of an additional dynamic node in a power efficient manner. This node is envisaged to be a platform whose primary purpose is to increase the capacity and power efficiency of the MANET. Given a specific network configuration the optimal location of an additional node is investigated. This node insertion is teamed with power adjustments of all the nodes carried out in a manner consistent with topology control. This approach is then compared to topology control methods not using an additional node. The simulations performed show that the technique described can significantly decrease the jamming experienced within a MANET, thereby increasing the network's capacity. Additional benefit is also observed in the power usage of the MANET falling, thereby increasing the operational lifetime of the network. From the results obtained it will be inferred that a simple distributed algorithm to find the optimal point is not a trivial exercise.
