AntNet算法在Ad Hoc网络QoS组播路由中的研究

由于网络拓扑结构变化频繁和节点能量有限的原因， Ad Hoc网络中的QoS组播路由算法必须能够尽快地感知网络中路径的能量状态并且自适应地改变组播路由。 AntNet 算法中的蚂蚁代理能够感知网络中各个子路径的能量状态和更新信息素，从而使组播路由能够衡量整个网络的能量变化情况，最后就找到了考虑到路径能量状态的QoS组播路由。仿真实验表明，该算法能够均衡节点能量从而提高网络性能。

AntNet-Based Multicast Routing Algorithm of Mobile Ad Hoc NetWorks

or some reasons such as dynamic network topology and limited energy of nodes, the multicast routing algorithm of Ad Hoc network must be aware of the energy status of network nodes and be very self-adaptive to alter the multicast route as soon as possible. In this paper, the ant-agent of AntNet algorithm can gather the energy status of paths and update the pheromone. As a result, the multicast route can evaluate the changes of energy in whole network. The results of simulation show that this algorithm can balance node energy and improve the performance.
