DSDV, DYMO, OLSR: Link Duration and Path Stability

TL;DR

This paper compares link duration and path stability of DSDV, DYMO, and OLSR routing protocols, enhances DYMO and OLSR, and evaluates their performance under various network conditions.

Contribution

It introduces enhancements to DYMO and OLSR protocols and provides a comparative analysis of their performance in terms of stability and efficiency.

Findings

DYMO outperforms DSDV, OLSR, and MOD-OLSR in key performance metrics.

Enhanced protocols show improved stability and packet delivery.

Trade-offs include higher routing overhead for better performance.

Abstract

In this paper, we evaluate and compare the impact of link duration and path stability of routing protocols; Destination Sequence Distance vector (DSDV), Dynamic MANET On- Demand (DYMO) and Optimized Link State Routing (OLSR) at different number of connections and node density. In order to improve the efficiency of selected protocols; we enhance DYMO and OLSR. Simulation and comparison of both default and enhanced routing protocols is carried out under the performance parameters; Packet Delivery Ratio (PDR), Average End-to End Delay (AE2ED) and Normalized Routing Overhead (NRO). From the results, we observe that DYMO performs better than DSDV, MOD-OLSR and OLSR in terms of PDR, AE2ED, link duration and path stability at the cost of high value of NRO.
