A Lightweight Threshold-Based Improvement on DSDV

چکیده
One of the main research challenges in mobile ad hoc networks (MANETs) is designing adaptive, scalable and low-cost routing protocols for these highly dynamic environments. In this paper, we propose a new improvement on DSDV, which is one of the most popular proactive routing protocols in MANETs. We introduce a new metric called hop change metric in order to represent the changes in the network topology due to mobility. We determine a threshold value based on this metric in order to decide the full update time dynamically and cost effectively. The proposed approach (LaDSDV) is compared with the original DSDV and ns-DSDV. Simulation results show that our threshold-based approach improves the packet delivery ratio and the packet drop rate significantly with a reasonable increase in the overhead and the end-to-end delay.
