An enhanced reactive dynamic source routing algorithm applied to mobile ad hoc networks

Even though the reactive dynamic source routing protocol (RDSR) has been shown via simulations to be mostly efficient among all the existed routing protocols, it increases transmission delay. To overcome the above drawback in the reactive ad hoc routing protocol, this paper proposes an enhanced reactive ad hoc network routing protocol: ERDSR (enhanced reactive dynamic source routing protocol). ERDSR chooses the route by using the bandwidth and the number of hops of the available paths, and regulates the value of send_timeout dynamically. Compared with RDSR by using ns-2 under various environments, ERDSR reduces the transmission delay and the average path length, and significantly improves the packet delivery ratio.
