چکیده
Received Dec 3, 2013 Revised Jan 7, 2014 Accepted Feb 3, 2014 The merits of 802.11s as the wireless mesh network standard provide a low cost and high independent scalability telemedicine infrastructure. However, challenges in degradation of performance as hops increase and the absent of Quality of Service (QoS) provision need to be resolved. The reliability and timely manner are the important factor for successful telemedicine service. This research investigates the use of 802.11s for telemedicine services. A new model of 802.11s based telemedicine infrastructure has been developed for this purpose. A non deterministic polynomial path selection is proposed to provide end-to-end QoS provisioning in 802.11s. A multi-metric called QoS Price metric is proposed as measurement of link quality. The QoS Price is derived from multi layers values that reflect telemedicine traffic requirement and the resource availability of the network. The proposed solution has modified the path management of 802.11s and added resource allocation in distributed scheme. Keyword:

Advanced operations research techniques for multi-constraint QoS routing in internet
Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...
متن کاملImproving Success Ratio in Multi-Constraint Quality of Service Routing
Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...
متن کاملQoS-sensitive routing for Real-time Multicasting
Multicast service with Quality of Service (QoS) guarantees is critical to commercial and real-time applications , such as telemedicine, video-conferencing, and virtual reality. The Internet is currently in the process of developing QoS architectures (e.g., Int-serv, Dii-serv) to support such applications. However, most multicast protocols, such as PIM and CBT, do not employ QoS-sensitive routin...

With the growth of wireless networks, Wireless Mesh Network (WMN) has appeared as an emerging key solution for broadband Internet access with a low-cost deployment. Moreover, providing QoS guarantees for real-time and streaming applications such as VoIP (Voice over IP) and VoD (Video on Demand) is a challenging issue in such environment. In this paper, we propose a hybrid wireless mesh architec...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
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...
