Modified distributed quality-of-service routing in wireless mobile ad-hoc networks [PDF]

open access: possible11th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.02CH37379), 2003
The QoS routing is a key function for the transmission and distribution of multimedia traffic across networks. However, their application in ad hoc networks is difficult because of the ever-changing nature of the network topology, and the inherently imprecision of routing state information. In this paper an efficient distributed routing algorithm based

Distributed aggregation service for mobile wireless ad hoc sensor networks

International Journal of Mobile Communications, 2007
This paper presents Cluster On-Demand Distance Vector Routing (CODV) algorithm for distributed aggregation service in mobile ad hoc sensor networks to achieve important networking requirements, including network scalability, load balancing, loss tolerance, and prolonged lifetime. CODV allows users to express simple queries and have them executed at the

Queueing Analysis of Distributed MAC in Wireless Ad Hoc Networks with Differentiated Services

2006 IEEE International Conference on Communications, 2006
A queueing analysis of a distributed and energy-aware medium access control (MAC) protocol is presented for wireless ad hoc networks with service differentiation. We consider a battery-powered node in the network with two different types of traffic, and model the node as a MAP/PH/1/K non-preemptive priority queue with multiple vacations to model the ...

Distributed Flow Admission Control for Multimedia Services Over Wireless Ad Hoc Networks

Wireless Personal Communications, 2006
In this paper we propose a novel Priority-based Distributed flow Admission Control (PDAC) protocol to provide Quality of Service (QoS) to multimedia applications over the Dynamic Source Routing (DSR) protocol-based wireless ad hoc networks. In contrast to short-term packet forwarding, medium and long-term multimedia and real-time traffic may benefit ...

Distributed flow admission control for real-time multimedia services over wireless ad hoc networks

Proceedings of the 2nd international conference on Mobile multimedia communications - MobiMedia '06, 2006
In this paper, we propose a novel Priority-based Distributed flow Admission Control (PDAC) protocol which adds enhancements to the existing Dynamic Source Routing (DSR) protocol in order to provide Quality of Service (QoS) to traffic flows belonging to realtime and multimedia applications in wireless ad hoc networks. PDAC allows a node to establish and/
