Information and Communication Technologies (ICTs) are extremely important for sustainable development for all countries. It can be used to make information available in the right form to the right user at the right time in faster and better way. Archeological sites, museums and old towns are some of the fields that can take great advantages of such technologies. These places need a particular ICTs...
The paper presents the flow-based model that was designed for solving dynamic queue balancing problem on the telecommunication network routers. Within the proposed model the problem of queue balancing was reduced to solution of the linear programming optimization problem. The research of the queue balancing process was performed by using flow-based model in regard to improve quality of service in...
Real-time applications such as multimedia streaming and video conferencing have quite stringent Quality of Service (QoS) requirements from the network, because they are more sensitive to available bandwidth and loss rate than non real-time traffic. To provide scalable and simple Quality of Service (QoS) mechanism for multicast services, Probe-Based Multicast Admission Control (PBMAC) scheme was proposed...
In this paper a flow-based model balancing queues at the nodes of MPLS-network is proposed. The novelty of the model is that it, in the contrast to the previously known models takes into account the features of the Traffic Engineering Queues technology. This technology has a purpose to ensuring load balancing of the node buffer resource.
Developing distributed applications for MANETs is a complex task due to the latter's bandwidth constrained nature. Further, in tactical MANETs, there is a need to prioritize traffic generated by distributed applications so that high priority traffic gets preferential access to the bandwidth constrained communication medium. Finally, applications must be designed to accommodate network bandwidth and...
In this paper an approach to the flow-based modeling of two-level routing in multiservice networks is considered. The model supports the source routing. At the low level - the level of edge routers - the routes are directly computed, and at the top level the received decisions are coordinated for excluding overloads of communication channels in a multiservice network.
In cognitive radio (CR) networks, the perceived reduction of application layer quality of service (QoS), such as multimedia distortion, by secondary users may impede the success of CR technologies. Most previous work in CR networks ignores application layer QoS. In this paper we take an integrated design approach to jointly optimize multimedia intra refreshing rate, an application layer parameter,...
Network centric unification of diverse communication and information sharing systems is a key objective for national defense. Overall, IP-convergence is the basis for seamlessly integrating the DoD SATCOM networking and information needs with the Global Information Grid (GIG). This paper explores IP networking with the emerging Regenerative Satellite Mesh-A (RSM-A) Ka band technology. The focus is...
In this paper, we propose and analyze a different channel allocation scheme in mobile cellular networks which not only gives priority to handoff calls but also tries to protect originating calls. We use channel reservation to protect handoff calls and in contrast, to protect originating calls, we set a maximum reservable channel, NG, in our scheme. In channel reservation schemes, there are some periods...
