Abstract:

The design and performance of a multi-path routing based on adaptive modulation and coding algorithm for mobile ad-hoc networks were presented. For achieving the minimum total delay, single-path or multi-paths would be selected to route packets, according to both channel condition and traffic load. Considering the costs and overheads of searching and spending of routing tables, the maximum two paths (minimum cost and secondary cost path) were taken into account. The simulation results show that the channel adaptive routing of maximum two-path can obtain better delay performance.
