This paper systematically evaluates how mobility affects the performance of six wireless routing protocols, analyzing trade-offs in throughput, delay, and routing load through extensive NS-2 simulations.

Contribution

It provides a comprehensive comparison of reactive and proactive protocols under mobility, revealing their performance trade-offs and ranking them based on key metrics.

Findings

Reactive protocols generally have lower routing load.

Proactive protocols offer lower end-to-end delay.

Mobility significantly impacts protocol performance.

Abstract

In this paper, we evaluate, analyze, and compare the impact of mobility on the behavior of three reactive protocols (AODV, DSR, DYMO) and three proactive protocols (DSDV, FSR, OLSR) in multi-hop wireless networks. We take into account throughput, end-to-end delay, and normalized routing load as performance parameters. Based upon the extensive simulation results in NS-2, we rank all of six protocols according to the performance parameters. Besides providing the interesting facts regarding the response of each protocol on varying mobilities and speeds, we also study the trade-offs, the routing protocols have to make. Such as, to achieve throughput, a protocol has to pay some cost in the form of increased end-to-end delay or routing overhead.
