Abstract: An improvement method based on frequency division multiple access (FDMA) for routing is put forward in mobile ad hoc networks. A new method employing collision detection mechanism which embodies the idea of control center transmission is used to announce the route failures. An analysis of this solution is followed to show its advantages in enhancing the capacity of overall networks and delays. The results can be used to demonstrate the good throughput over previous methods.
