The current best effort approach to quality of service in the Internet can no longer satisfy a diverse variety of customer service requirements , and that is why there is a need for alternative strategies. What the Internet needs is a mechanism for providing a fine-grained per-flow quality of service that does not cause network congestion and keeps overall(More)
The current best effort approach to Quality of Service in the Internet can no longer satisfy a diverse variety of customer service requirements, because of which there is a need for alternative strategies. A promising approach for dealing with this problem is a method called Load Distribution Scheme (LDS) which dynamically adjusts traffic load at the(More)
SUMMARY The problem of fair distribution of available bandwidth among traffic flows or aggregates remains an essential issue in computer networks. This paper introduces a novel approach, called the Exact Bandwidth Distribution Scheme (X-BDS), for dynamic and fair distribution of available bandwidth among individual flows. In this approach, the edge routers(More)
The national importance of creating "content reflecting cutting edge developments in STEM fields" has been recognized the National Science Foundation. The National Research Council has also noted that creating engaging laboratory and classroom experiences is a challenge to effective undergraduate education in STEM disciplines. In this paper we present our(More)
— Location-aided routing (LAR) is a mechanism which attempts to reduce the control message overhead of Ad-hoc on-demand distance vector (AODV) routing protocol by flooding only the portion of the network that is likely to contain the route to destination. LAR takes advantage of Global Positioning System (GPS) coordinates to identify a possible location of(More)
Ad-Hoc On-Demand Distance Vector (AODV) is a routing protocol for mobile ad hoc networks (MANET). AODV floods the network with control messages to discover a route to the destination, which often results in a large number of control packets traveling through the network. This paper introduces the design and implementation of GeoAODV routing protocol for(More)
Despite numerous efforts, the problem of providing per-flow Quality of Service in a scalable manner still remains an active area of research. This paper introduces a scalable architecture for support of per-flow bandwidth guarantees, called the Bandwidth Distribution Scheme (BDS). The BDS maintains aggregate flow information in the network core and(More)
Recently a large number of approaches to service differentiation have appeared in the literature. Most of these approaches are based on the Differentiated Services (DiffServ) Architecture proposed by IETF and they have been evaluated in a number of independent studies. It is widely acknowledged that the Differentiated Services approach provides proper(More)
