On the Performance of the Current MANET Routing Protocols for VoIP, HTTP, and FTP Applications

Abstract

The recent advances of ensemble mobile environment of smart devices with embedded sensors have enabled the MANET to play a key role in the smart cities as well as WSN and WMN. However, these smart devices are still limited in terms of energy, processor, and memory. Moreover, the efficient routing for reliable network connectivity at anytime, anywhere, and about everything is still a challenge in multihop wireless networks. This paper evaluates the QoS and energy efficiency of three active routing protocols: (i) OLSRv2, a successor to OLSR, (ii) DYMO, a successor to both DSR and AODV, and (iii) MP-OLSR multipath extension to OLSRv2. In contrast to the related previous works which focused only on CBR traffic without considering the influence of specific traffic types on the performance of routing protocols, this work focused on this area from a different perspective. It evaluates the performance of three internet-based traffic types that can be used in the smart city applications: VoIP, HTTP, and FTP using different simulation models. The impact of the network density, load traffic, and nodes mobility on the considered protocols was evaluated by considering particular performance metrics for each traffic application. Based on the results, the study concludes by presenting useful recommendations for future work.

Enhancement of Routing Protocols for Mobile Adhoc Network

“…But for commercial application of adhoc networks like replacing the infrastructured services by adhoc services the modified protocol is not suitable for high traffic and scalability.. As a result the performance can be classified as working well under application specific scenarios. The modified protocol performs better in areas like battlefield survivability and disaster recovery [7],{8}.The future work includes expanding this idea for a hierarchical network like cluster head gateway switch routing and reducing the delay in hibernation by means of a route cache.…”

Algorithmic Identification of the Best WLAN Protocol and Network Architecture for Internet-Based Applications

“…Another drawback associated with the (Pérez et al 2015) and the (Anouari and Haqiq, 2013) approaches, is that they only consider the evaluation of the algorithm using one IEEE standard, particularly IEEE 802.11e and 802.16. Similarly, (AlAlawi & Al-Aqrabi, 2015) and (Jabbar et al 2014) evaluate different IEEE technologies using a varied number of nodes, while only considering one network architecture such as ESS and IBSS, respectively. On the other hand, methods such as (Salah, 2006) and (Sllame et al 2015) evaluate the network on the basis of a fixed number of nodes, 9 and 15, respectively.…”

Multi-criteria based multipath OLSR for battery and queue-aware routing in multi-hop ad hoc wireless networks

“…In executing each experiment, the traffic type has a serious impact on the performance of routing protocols [47]. Moreover, the change in the traffic model parameters such as number of flows, number of packets, or packet size will affect the congestion level in the network.…”
