Qos-Aware Routing for Efficiently Transmitting Multimedia Data in MANETS

Due to the complexity of real-time multimedia applications in MANET, various problems inherent to QoS provision inhibit the successful transmission of multimedia data. A major problem is related to the unpartitioned network which makes the network hard-manageable. The energy constraints are challenges facedas some nodes are dead due to their low battery power. Storm problems are related to the broadcasting nature of some routing protocols. Other major problems relate to the fairness and securityissues often neglected during data transmission.To address those problems, various robust QoS routing, multi-algorithm mechanisms have been proposed in this study, each one being a mixture of important QoS provision techniques namelyAnt Colony with Fuzzy Optimization techniques, Genetic Algorithms, Multicast Techniques, Power-Aware Routing Schemes, Clustering Mechanisms, Intrusion Detection Techniques, and Packet Scheduling schemes.

QAMACF (QoS-Aware transmission for Multimedia applications using Ant Colony with Fuzzy optimization), a prominent QoS protocol which is a combination of multicast techniques and ant colony with fuzzy optimization mechanisms was first proposed. GDAQM (Genetic with DPD for Attaining high QoS in MANETs) which is a combination of both Genetic and MDPD-k scheduling algorithms was implemented next.  The third proposed scheme is MARMAQS (Multi-Algorithm Routing Mechanism for Acquiring high Quality of Service in MANET) consisting of QoS techniques namely lifetime prediction routing, packet scheduling, and the intrusion detection techniques. FSR-CAES (Full-Featured Secure Routing Clustering Algorithm with Energy-Aware and Scheduling capabilities for increasing QoS in MANET), a combination of numerous algorithms, each one containing one of the previously mentioned problems was fourthly proposed.  Using the NS-2 simulator, the proposed schemes performed well by highly increasing the QoS during multimedia data transmission and finally, a comparative evaluation of the proposed protocols was then conducted, each scheme performed well for some experimentations and outperformed during others, hence, it was proved that our proposed protocols are well suited for real-time multimedia applications.
