Analysis and evaluation optimization dynamic source routing (DSR) protocol in Mobile Adhoc network based on ant algorithm

Mobile Adhoc is a network that does not have the infrastructure and have the ability to manage its network independently, in the future this network predicted to be the key to the development of network applications. Routing protocols have an important role in this network, a lot of research has been done. In this research we use optimized routing protocols in mobile ad hoc network (MANET), the optimization is done on the routing protocol DSR (Dynamic Source Routing) which is reactive routing protocol using ant algorithm. Then we analysis and evaluated the performance of this routing protocol in various scenario and compared the result with standard DSR routing protocol. The results of this research indicate the performance of DSR-ant has a better performance. In all the scenario, DSR-ant has 48% smaller delay, 1.37 times smaller hop count, and throughput up to 3.6 times larger, but DSR-ant has routing overhead 58% larger than standard DSR. The result in velocity, pause time, and traffic connection scenario, show the result consistency, DSR optimization using ant algorithm can improved performance with a smaller delay and the number hop to transfer information between node. DSR-ant gain larger throughput but resulting in higher routing overhead than DSR standard due the effort of DSR-ant to find the best path.
