A practical scenario to realize Ad hoc network based on the Linux operation system is proposed in this paper. A practical test network composed of several nodes is built and DSR (Dynamic Source Routing) protocol is selected to run on the test network. Meanwhile, in order to obtain better support for real time multimedia services, an improved DSR protocol considering delay demand is also testified...
This paper has introduced several QoS routing protocols in the ad hoc networks. And it elaborates the development tendency in the future through comparing several important QoS routing protocols in the ad hoc networks.
This paper introduces a constrained QoS multicast routing algorithm in Ad hoc (CQMRA). The key idea of proposed algorithm is to construct the new metric-entropy and select the stability path with the help of entropy metric to reduce the number of route reconstruction so as to provide QoS guarantee in Adhoc. The simulation results show that the proposed approach and parameters provide an accurate and...
A multimetric QoS routing protocol (MQOLSR) is proposed in this paper, which providing different QoS for different applications flow in an ad hoc network. The protocol, which integrates QoS measurement and packet forwarding, expands the topology discovery and routing computing mechanism of the OLSR protocol. It can provide different routing and forwarding service according to different application...
Most of flooding algorithm of recent Ad Hoc multicast routing protocols are suitable under specific networks conditions. If the condition changes like increasing the number of multicast source nodes and networks nodes or having higher node speed and more traffic loads, they will not work well. To provide multicast routing support for a wide range of operational condition, we propose a new protocol...
Considering the high data rate of ultra-wideband (UWB) system, paper develops a ranging-aided quality-of-service (QoS) routing protocol. In this protocol, we introduce two QoS parameters: transfer bit rate and end-to-end delay. We optimize these two parameters to choose routing and change routing in time using UWB ranging. This protocol provides a steady routing for high data rate operation. This...
