| 中文摘要: |
| 提出了一种移动自组网中的拓扑控制算法MATC(multi-rate aware topology control),该算法充分考虑了无线环境中固有的多速率特性,在保证原有网络连接性的前提下删除部分低速链路,为上层的路由协议构造一个良好的拓扑,确保按需路由协议能够在一跳范围内发现最优路由.大量仿真结果表明,MATC对网络性能有较大的提高. |
| 英文摘要: |
| The problem of topology control in multi-rate mobile ad hoc networks is studied and a multi-rate aware topology control algorithm (MATC) is proposed in the paper. MATC fully takes the inherent multi-rate property of wireless network into account. It removes some low rate links while preserving the connectivity of the network. On the basis of MATC, on-demand routing protocols can find the optimal route in one-hop range. Extensive simulations show that MATC can significantly improve the network throughput. |
