SDDSR: Sequence Driven Dynamic Source Routing for Ad Hoc Networks

Mobile ad-hoc networks are becoming more popular as the use of mobile computers is increasing. The biggest challenge facing such networks is continuous and random change in the topology. Table driven routing protocols where not designed for such networks. For this reason new routing protocols that can handle continuous change of topology where created. Two popular protocols are Dynamic Source Routing (DSR), and Ad-hoc On-demand Distance Vector (AODV). DSR has the advantage of making heavy use of routing information to reduce the routing load, where as AODV has the advantage of using sequence numbers, which guarantees that at all time we are using non-stale routing entries. In this paper, we present the implementation of Sequence Driven Dynamic Source Routing (SDDSR). SDDSR is an on-demand routing protocol, which builds upon DSR and AODV. We use the NS-2 simulator to show the experimental results of the new protocol. The results showed better packet delivery as well as less routing load.
