SWAN: Service Differentiation in Stateless Wireless Ad Hoc Networks
نویسندگان
چکیده
mobility or traffic overload conditions. We use the term " soft " real-time services to indicate that real-time sessions could be regulated or dropped due to mobility or excessive traffic overloading at mobile wireless routers. SWAN is designed to limit such conditions, however. A novel aspect of SWAN is that it does not require the support of a QOS-capable MAC. Rather, soft real-time services are built using existing best effort wireless MAC technology. Simulation, analysis, and results from an experimental wireless testbed show that real-time applications experience low and stable delays under various multi-hop, traffic and mobility conditions. The wireless testbed and ns-2 simulator source code are available from the Web (comet.columbia.edu/swan).

Service Differentiation in Mobile Ad hoc Networks
Mobile Ad hoc Network (MANET), a collection of nodes that form a multi-hop wireless network, is emerging as an important technology in the present and near future. MANETs are being used in a variety of applications from emergency rescue to sensor networks. With the expansion of real-time applications for this type of networks, the need for quality of service (QoS) support has become essential. ...
متن کاملSupporting Service Differentiation for Real-Time and Best-Effort Traffic in Stateless Wireless Ad Hoc Networks (SWAN)
We propose SWAN, a stateless network model which uses distributed control algorithms to deliver service differentiation in mobile wireless ad hoc networks in a simple, scalable and robust manner. The proposed architecture is designed to handle both realtime UDP traffic, and best effort UDP and TCP traffic without the need for the introduction and management of per-flow state information in the ...
متن کاملToward Service Differentiation Based on a Semi-Stateless Approach for Mobile Ad Hoc Networks
This paper discusses an approach of QoS service differentiation in mobile ad hoc networks. We aim to investigate the performances of the proposed semi-stateless approach, named “MARS”, over the existing stateless approaches. Mars supports both real-time UDP traffic, and best-effort UDP and TCP traffic. The main objective of MARS is to minimize the end-to-end delay of traffic. The proposed model...

This paper analyzes the provision of end-to-end Quality of Service between nodes in a mobile ad hoc network and a fixed IP network that supports Differentiated Services. The ad hoc network incorporates the Stateless Wireless Ad Hoc Networks (SWAN) model to perform admission control for real-time traffic flows. We propose a new protocol, named DS-SWAN (Differentiated Services-SWAN), where end-to...
