Abstract
Although, all prior works improved routing on MANETs, there is no strong advancement on QoS. One of the newest challenges to improve quality of routing in MANETs is combining the Genetic and Fuzzy algorithms into routing protocols. The improvements on routing QoS are approached by using Genetic and Fuzzy algorithms in this project. In cause of storing route information during route discovery, the DSR routing protocol is chosen by this project. First of all, the suggested protocol in this project added Current Time into DSR header. So, next intermediate node can obtain its previous link’s cost by this attachment and adds the Link Cost to route discovery packet. Then, when the route discovery packet received to destination node, it will expect for other packets till end of packet TTL. Next, the destination node will use collected packets in Genetic Algorithm to find the two optimum routes. Finally, the destination node sends these routes to source node. Next improvement is using Fuzzy Triangle Numbers to change route update. In this case, the suggested protocol uses route error packets’ count and also Triangle Numbers to change route update period time.
