    ABSTRACT: Quality of Service (QoS) support for Mobile Ad hoc Networks (MANETs) is an exigent task due to dynamic topology and limited resource. To support QoS, the link state information such as delay, bandwidth, jitter, cost, error rate and node energy in the network should be available and manageable. The focus of this paper is extending the scope to QoS routing procedure, to inform the source about QoS available to any destination in the wireless network. However, existing QoS routing solutions were dealt with only one or two of the QoS parameters. It is important that MANETs should provide QoS support routing, such as acceptable delay, jitter and energy in the case of multimedia and real time applications. This paper proposes a QoS Dynamic Source Routing (DSR) protocol using Ant Colony Optimization (ACO) called Ant DSR (ADSR).The performance of DSR and ADSR are analyzed using network simulator-2. ADSR produces better results than the existing DSR in terms of delay, energy, jitter and throughput.

    Article: A Swarm-based Distance Vector Routing to Support Multiple Quality of Service (QoS) Metrics in Mobile Adhoc Networks

    ABSTRACT: Quality of Service support for Mobile Ad-hoc Networks is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. A fundamental problem in QoS routing is to find a path between a source and destination that satisfies two or more end-to-end QoS constraints. In this paper a novel QoS routing algorithm called Swarm-based Distance Vector Routing based on ant colony optimization is proposed to support delay, jitter and energy constraints. The simulation resultsof SDVR are compared with the reactive routing protocol Adhoc On demand Distance Vector routing. SDVR produces better performance than AODV in terms of packet delivery ratio, throughput, end-toend delay, energy, and jitter.
