Quality of Service (QoS) of video streaming service over wireless and mobile network is determined by many intermingled factors. Some of the factors can be adjusted. Video resolution, audio rate, and bandwidth are among of them. Other factors are not fully controllable such as network throughput, delay, and packet lost probability. In order to increase user satisfaction, efforts to make better quality...
We study a mobile wireless network where groups or clusters of nodes are intermittently connected via mobile "carriers'' (the carriers provide connectivity over time among different clusters of nodes). Over such networks (an instantiation of a delay tolerant network), it is well-known that traditional routing algorithms perform very poorly. In this paper, we propose a two-level Back- Pressure...
Ad-hoc network is a self organizing and adaptive in nature. Since it is a dynamic multihop wireless network and established by a cluster of mobile nodes on a shared wireless channel. The transitive closure of the neighborhood of all the hosts or nodes in the set of mobiles under consideration forms network. Each node is potentially a router and it is possible to dynamically establish routes by changing...
Mobile ad hoc networks are a wireless network in which each node is vested with the responsibility to act as a router. The individual nodes are constrained by the resources such as battery power. To achieve maximum throughput with the available resources the nodes might behave selfishly. This could lead to severe performance degradation in network throughput, packet delivery ratio, packet loss increment,...
The prediction of performance in Manet (mobile ad-hoc network) used to improve the technology development. The proposed analysis used how to design a network according to the applications of mobile adhoc network experiments with different workloads. This paper shows the variations of any parameter must affect the performance of mobile adhoc network. The average end-to-end delay, throughput and average...
Several gateway selection schemes have been proposed that select gateway nodes based on single QoS metric, for instance link availability, link capacity etc. or multiple non-QoS metrics, such as the combination of gateway node speed, residual energy, and number of hops, for mobile ad hoc networks (MANETs). Each scheme just focuses to improve only single network performance such as network throughput,...
Clustering is an important concept for mobile ad hoc networks (MANETs), because clustering makes it possible to guarantee basic levels of system performance, such as throughput, delay and also security issues such as availability, in the presence of both mobility and large number mobile terminals. Many clustering protocols for MANETs have been proposed in the literature. As a newly proposed weighing-based...
