Performance Analysis of Node-Disjoint Multipath Routing for Mobile Ad-hoc Networks based on QoS

چکیده
Recently, quality-of-service routing in dynamic, wireless multi-hop ad hoc networks becomes a hot research topic, and various QoS protocols are proposed Even so, popular QoS routing protocols rarely provide multiple routes. Once links break due to node mobility, establishment of new routes leads to large control overhead and more end-to-end delay. In MANETs to support multimedia applications such as video and voice require an efficient routing protocol and quality of service (QoS) mechanism. Node-Disjoint Multipath Routing Protocol (NDMR) is a practical protocol in MANETs: it reduces routing overhead dramatically and achieves multiple node-disjoint routing paths. In MANETs QoS support is an important issue as best-effort routing is not efficient for supporting multimedia applications. This paper presents a novel adaptation of NDMR, QoS enabled NDMR, which introduces agent-based SLA management. This enhancement allows for the intelligent selection of node-disjoint routes based on network conditions, so fulfilling the QoS requirements of Service Level Agreements (SLAs).

Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

Mobile Ad hoc Networks are highly dynamic networks. Quality of Service (QoS) routing in such networks is usually limited by the network breakage due to either node mobility or energy depletion of the mobile nodes. To fulfill certain quality parameters, and to achieve network stability, presence of multiple node-disjoint paths becomes essential. Such paths aid in the optimal traffic distribution...
