Internet is widely used in the fast growing world. So the wired and wireless networks are mainly used in an active area and there are many limitations in the wireless mesh network. The Congestion Control in the Network field is by means of Scheduling packets from different traffic flows for processing at a specific node is done. In Wireless Adhoc Network, a channel assignment has to balance the...

This paper provides network designers and operators with simple guidelines on traffic measurements and efficiency evaluation of various channel allocation schemes in digital mobile telecommunications networks. The paper evaluates the efficiency obtained by implementing the following channel allocation schemes: 1) fixed uniform channel allocation (FUCA); 2) fixed nonuniform channel allocation (F...

We study a repairable item inventory system under limited repair capacity and nonstationary Poisson demands, motivated by corrective maintenance of military equipment. Our goal is to minimize the cost of both spare and repair resource allocation. We propose an efficient analytical model that combines optimization modeling and queuing theory.

In this work, we examine the downstream impediments of centralized Ethernet passive optical networks supporting LAN emulation [inter-Optical Network Units communication(ONU)]. The available downstream bandwidth in the centralized scheme is reduced due to LAN emulation and upstream bandwidth allocation functions. The reduction in available downstream bandwidth results in degraded downstream perf...

This paper presents a traffic control agent that can perform the dynamic resource allocation by controlling traffic flows on a DiffServ network. In addition, this paper presents a router that can support DiffServ on Linux to support selective QoS in IP network environment. To implement a method for selective traffic transmission based on priority on a DiffServ router, this paper changes the que...

Despite a decade of research and development, multicast has not yet been deployed on a global scale. Among the difficulties with the current infrastructure are intermulticast fairness support, multicast congestion control, and multicast routing. In this paper, we focus on the inter-multicast fairness issue which addresses the way how the network resources are shared between competing multicast ...

Current Medium Access Control (MAC) protocols for data collection scenarios with a large number of nodes that generate bursty traffic are based on Low-Power Listening (LPL) for network synchronization and Frame Slotted ALOHA (FSA) as the channel access mechanism. However, FSA has an efficiency bounded to 36.8% due to contention effects, which reduces packet throughput and increases energy consu...

In the context of computer networks, customers represent packets (or frames, and we shall not make the distinction here), and service represents the assignment of packets to communication links. For instance, if a link (server) has a bandwidth of B bps (service rate), then the service time for a packet (customer) assigned to that link will be L/B, where L is the size of the packet in bits (incl...

Many audio and video stream applications in the Internet require good network performance but not perfect reliability. Such applications should employ congestion control and should not shut down the TCP ows by restricting bu ering too much. However, the Internet is not a small local community, and it is impossible to rely on all developers to incorporate end-to-end congestion control in their I...

This paper examines the issue of dynamically scheduling applications on a wide-area network computing system. We construct a simulation model for wide-area task allocation problem and study the performance of the proposed algorithm under different conditions. The simulation results indicate that the wide-area scheduling algorithm is sensitive to several parameters including machine failure rate...
