An ad hoc network is a collection of computers (nodes)that cooperate to forward packets for each other over a multihop wireless network. Users of such networks may wish to use demanding applications such as Voice over IP, videoconferencing, and streaming media when they are connected through an ad hoc network. Because over provisioning, a common technique in wired networks, is often impractical in...
Due to the dynamic topology, limited and shared bandwidth of the mobile ad hoc network (MANET), providing Quality of Service (QoS) for MANET-based Networked Control Systems (NCS) is a challenging task. This paper integrates the concept of choosing stable route according to Received Signal Strength Indication (RSSI) into AQOR. Considering the data packet transmission characters of NCS, we let the intermediate...
In order to satisfy the demand of rapid growth of multimedia applications in mobile ad hoc network (MANET), this paper proposed an improved QoS routing algorithm based on AODV. It adopted the mechanism of intermediate request returning, selected flooding, and local route recovery. Results from extensive performance simulation of the proposed protocol demonstrate that it reduces the control overhead...
Provision of quality of service (QoS) in an ad hoc network is a challenging task due to their inherent characteristics. In this paper, we present a routing protocol for QoS provisioning in mobile ad hoc networks. Our protocol tries to discover multiple node-disjoint paths between a given source and a destination that are able to satisfy QoS requirements in terms of bandwidth required by a flow of...
Most of the researcher worked on routing protocol in mobile ad hoc network but very less work has been done in data access. Caching in frequently accessed data in multi hop environment can improve the availability and performance of the network. However designing efficient distributed caching technique is not an easy task because of the movement of nodes. Connected dominating set is a frequently used...
Based on the analysis of the node selfishness and the drawback of min-hop selection method as the unique routing selection criteria in ad hoc networks, a non-intrusive multi-metric ad hoc routing protocol-NIMR is presented. By computing and storing the node fame, NIMR greatly attenuates the influence of node selfishness; By crossing-design between MAC layer and network layer, we employ a non-intrusive...
Video capture and transmission play an important role in mobile ad hoc network (MANET) applications, and the routing protocol has vital impacts on the design of network performance. In this paper we designed and achieved an embedded video capture and transmission system which used an improved routing protocol AODV-SBR (AODV-simple backup route). The results indicated the video transmission system...
The design of QoS routing protocols for mobile ad hoc networks is a challenging issue. In selecting the most optimal route from source to destination, one has to choose from a set of routes with the corresponding connectivity qualities. In this paper, we proposed a modeling scheme that implement QoS routing using genetic algorithm. The route selected had to satisfy bandwidth, delay and node connectivity...
