Next generation wireless mobile networks is a vast area of research and has many design issues like throughput, delay, packet loss, etc. which deals with data transmission and packet scheduling techniques. Based on the above issues, we focus on data packet delivery based on priority and fairness with minimum delay and jitter. In this proposed paper, we are dealing with packet scheduling of mult...

A fundamental characteristic of the majority of communications networks is the mean message delay. In a packet-switching network, the mean packet and message delay may differ considerably from each other, and their distribution will often take different forms. The mean message delay depends both on the mean packet delay and on the dispersion of the packet delay. Obviously, by reducing the mean ...

The major problem of network security in present years is DoS (Denial of Service) attacks, in order to protect the network from these attacks a research is implemented in the key streams of network security. Packet marking is always required to track few details of packet like its source and the status toward reaching the destination. In most of the cases, packets transmitted by a source are lo...

The complexity of networks has outpaced our tools to debug them; today, administrators use manual tools to diagnose problems. In this paper, we show how packet histories—the full stories of every packet’s journey through the network—can simplify network diagnosis. To demonstrate the usefulness of packet histories and the practical feasibility of constructing them, we built NetSight, an extensib...

By introducing video-quality adaptation mechanisms into intermediate network equipments using active network technologies, we can provide users with video distribution services taking into account client-to-client heterogeneity in terms of available bandwidth, performance of client systems, and user’s preferences about video quality. In this paper, we designed and implemented an active video-qu...

Abstract   The streamed audio video (AV) content for IPTV across mobile WiMAX channel, the different schemes were discussed to reduce the noise, packet loss and latency. The objective of this paper is to verify the effectiveness of forward error correction (FEC) techniques and to suggest the techniques for robustness problems and to analysis the issues either due to AV coding encoding or due to...

Protocol design requires understanding state distributed across many nodes, complex message exchanges, and with competing traÆc. Traditional analysis tools (such as packet traces) too often hide protocol dynamics in a mass of extraneous detail. This paper presents nam , a network animator that provides packet-level animation and protocol-speci c graphs to aid the design and debugging of new net...

One of the main challenges in wireless sensor network is energy problem and life cycle of nodes in networks. Several methods can be used for increasing life cycle of nodes. One of these methods is load balancing in nodes while transmitting data from source to destination. Directed diffusion algorithm is one of declared methods in wireless sensor networks which is data-oriented algorithm. Direct...
