Collection of wireless nodes forms together to communicate each other in the network without infrastructure less and any access point along with characteristics freedom mobility is called Mobile Adhoc Network. Transmitting packets from source destination plays vital role MANET. When a Packet not delivered properly at , its affects performance Due this can subject falls on packet missing also va...

Random Early Detection (RED) is one of the most commonly used Active Queue Management (AQM) algorithms that is recommended by IETF for deployment in the network. Although RED provides low average queuing delay and high throughput at the same time, but effectiveness of RED is highly sensitive to the RED parameters setting. As network condition varies largely, setting RED's parameters with fixed ...

This paper tries to estimate the capital investment required for the fixed-telephony network switching equipment as demanded by the fourth national development plan. As a first step, the Cobb-Douglas model is used as a successful demand forecasting model to estimate the demand over the target years. Then, an architectural plan is developed for the fixed-telephony switching network that takes in...

Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...

In this paper, five different variants of interconnection networks such as Hypercube Network, Folded Hypercube Network, Multiply Twisted Hypercube Network, Recursive Circulant Hypercube Network and Multiple Reduced Hypercube Network are illustrated using Network Simulator and various physical and logical factors such as time, size of the packet, type of packet, speed, coverage and packet loss a...

Communication networks supporting real-time tasks need to guarantee timely delivery of critical data and commands. Worst-case delay performance of these networks can be analyzed using deterministic network calculus. In this report, we identify the discrepancy between existing bit-oriented delay bounding methods and packet-oriented behaviors of network devices. An optimization-based bit-oriented...

Fighting packet loss in optical packet-switched networks has been a priority in the optical research community in recent years. In this short paper, we present a scheme which utilizes both forward error correction at the ingress node and in-network coding at intermediary optical packet switches to reduce packet loss due to contention at the network layer. Initial analysis shows that if used in ...
