A Framework for Integrated Routing, Scheduling and Traffic Management (FIRST) in Ad Hoc Networks is introduced. Unicast and multicast routes are established in coordination with the scheduling of transmissions and bandwidth reservations in a way that bandwidth and delay guarantees can be enforced on a per-hop and end-to-end basis. Results from detailed simulation experiments show that, compared to...
In this paper we propose admission control and multipath routing algorithm for differentiated services (DiffServ) based networks (ACMRA). The basic DiffServ architecture lacks the admission control mechanism thus injecting more QoS sensitive traffic into the network can cause congestion at the core of the network. ACMRA combines the admission control with route finding phase and our routing protocol...
As a result of perceived limitations of TCP/IP in supporting high-throughput applications, significant efforts have recently been devoted to develop alternative architectures based on the concept of advance channel reservation. In this paper, we develop a polynomial-time algorithmic framework, called graded channel reservation (GCR), to support the implementation of such architectures. This framework...
The Suburban Ad Hoc Network (SAHN) is a cooperative ad hoc wireless mesh network. Nodes are owned and operated by end-users without reliance on central infrastructure. It provides symmetrical bandwidth allowing peer-to-peer services and distributed servers. We minimize the use of scarce unlicensed RF spectrum supported by Smart Antenna technology. RF interference in such networks and techniques and...
Computer network is an important phenomenon for digital information world. Computer network having the various problem due to more demand such as congestion control security, reliability, scalability, fairness etc. Multicast service helps computer network to flow information from one end to another end. In this paper, we provide BDQP approach to minimize the congestion control. NS-2 result shows,...
This paper describes an Enhanced Bandwidth Reservation Algorithm (EBRA) which introduces a new metric of Allocated Counter (AC) for considering multiple reservations in the same media access slot (MAS) for distributed UWB (Ultra Wideband) network. By considering bother call success rate and QoS (quality-of-service) constrain of establishing route, EBRA allows multiple reservation requests for the...
