Performance evaluation of proactive multipath routing protocol for ubiquitous networks

During the past years, a dramatic increase of peripheral self organised autonomic networks interworking with the traditional infrastructure networks has been highly noticed. Mobile Ad-Hoc Networks (MANETs) have become an interesting topic for research because of their independent nature in terms of network infrastructure and can play a vital role in future Internet communication. A lot of effort has been made in designing efficient routing protocols for MANETs, mainly because of their unique characteristics, such as dynamic topology, high mobility and limited bandwidth. In this paper we evaluate the performance of our Multipath-ChaMeLeon (M-CML) routing protocol and compare to other proactive protocols; Optimised Link State Protocol (OLSR) and Destination-Sequenced Distance Vector (DSDV). For this reason, we have considered 2 different scenarios for MANETs by varying the number of nodes and speed values using the NS-3 simulator. The Quality of Service (QoS) metrics we have taken into account are: packet delivery ratio, end-to-end delay, normalised routing load and energy consumption. The acquired results indicate that M-CML routing protocol reduces the effects of unstable communication links, while at the same time improves the performance of the network.
