摘　　要： 为解决自组网中功率控制引发的碰撞问题,通过引入多信道技术,结合网络层最小功率路由策略,实现了基于多信道功率可控的自组织网络架构MCBPC。该架构控制了拓扑结构的频繁变化,降低了因功率控制带来的碰撞机率,并实现了节省能量的目的。通过NS-2仿真实验验证,相比基于802.11的AODV架构,MCBPC在成功递交分组数、网络生存时间上均提高了90%以上,分组成功递交率也提高达30%以上。 To solve the collision problem brought by power control in mobile ad-hoc network （MANET）, multi-channel MAC protocol and on-demand minimum energy routing protocol were employed, to carry out a multi-channel based power control ad hoc network, MCBPC. This architecture controlled the frequent changes of topology, decreased the probability of contact brought by power control, and achieved the goal of energy conservation. Simulation results indicate that compared with AODV @ IEEE 802.11 approaches, the proposed MCBPC solution achieves about 90% increase in the throughput and network lifetime, and 30% increase in the packet delivery ratio.
