无线多播最优资源分配策略是无线Ad Hoc网络的核心问题.本文提出自适应多播控制算法（AMCAdaptive Multicast Control）,采用分段效用函数精确量化用户感知,降低无效带宽分配次数,使之适应中速及高速移动Ad Hoc网络;引入单位资源效用参数和接入判决机制,改善原有模型中带宽平均分配造成的资源浪费;采用竞价机制,提高存在差异带宽期望的异构多播业务流服务质量.仿真结果表明,AMC策略对移动Ad Hoc网络状态改变具有优良的自适应性能,尤其适用动态网络的异构分层多播业务流.

英文摘要：

Optimal resource allocation is the core problem in wireless multicast. An adaptive Muldcast Control algorithm （AMC） is proposed. It uses segmented bandwidth allocation to reduce iterations for medium-speed and high-speed mobile Ad Hoc network. It overcomes the disadvantage of average resource allocation by adopting marginal utility and adaptive access decision mechanism. And a bidding mechanism is used to improve the quality of heterogeneous bandwidth demanding for multicast traffic. Simulation results show that AMC policy has excellent performance for mobile network, especially for layered heterogeneous multi- cast in dynamic network condition.
