The research project deals with the investigation of various types of routing algorithms and the techniques available for evaluating the performance of these algorithms. A minimum delay adaptive routing algorithm, developed by R G ftallager is selected. The overall performance of a particular network consisting of randomly distributed nodtts is optimised using the algorithm. The performance of the network is optimized by minimizing the average packet delays. A simulation program is used to determines the performance of the netuork. The minimum delay routing algorithm provides a 30 to 40 percent improvement on the average packet delays compared to a static least cost, algorithm. The improvement is obtained once the adaptive routing algorithm has been carefully adapted to the network in which it is implemented.enThesis
