This paper presents Random Early Detection (RED) gateways
for congestion avoidance in packet-switched networks.
The gateway detects incipient congestion by computing
the average queue size. The gateway could notify
connections of congestion either by dropping packets arriving
at the gateway or by setting a bit in packet headers.
When the average queue size exceeds a preset threshold,
the gateway drops or marks each arriving packet with a
certain probability, where the exact probability is a function
of the average queue size.

Proactive routing protocol maintains constant and updated routing information for each pair of networking nodes by propagating route updates proactively at fixed interval of time. The periodic and event-driven messages are responsible for route establishment and route maintenance. The Destination-Sequenced Distance Vector (DSDV) protocol is the commonly used proactive routing protocol in mobile ad hoc network (MANET). In DSDV, each node maintains a routing table with one route entry for each destination in which the shortest path is recorded. I ....etc

Abstract
In the conventional mobile ad hoc network (MANET) systems' route rediscovery methods, there exists route failure in all route discovery methods resulting in data loss and communication overheads. Hence, the routing has to be done in accordance with mobility character of the network. In this manuscript, a particle swarm optimization (PSO)-based lifetime prediction algorithm for route recovery in MANET has been proposed. This technique predicts the lifetime of page link and node in the available bandwidth b ....etc

A group of sensor nodes work
collaboratively to perform a common application. In
many WSN applications, the sensor nodes are
battery driven and they are often very difficult to
recharge or change the batteries. Prolonging
network lifetimes a critical issue. Sensors often have
long period between transmissions. This mechanism
allows to identify replicas that are formed in the
mobile sensor network. These replicas are formed
due to the node replication attack in which an
adversary compromises one node, fabricate many
replicas having th ....etc

TRANSILLUMINATION IMAGING FOR EARLY SKIN CANCER DETECTION



I. INTRODUCTION
Frequent screening of suspicious skin pigmentations is a very effective approach for detecting skin cancers before they become lethal, since early changes in a malignant nevus typically consist in the development of an irregular pigmentation pattern. However, visual detection of melanomas by a dermatologist has an average diagnostic accuracy of only 58% , but it can be improved using imaging technique ....etc

The nodes of wireless sensor networks, with limited computing, communicating and sensing capabilities as well as limited energy, can make the best use themselves to gather data from sensor nodes to Base Station (BS) by using excellent network topologies, optimized routing schemes or data fusion algorithms in order gain the lifetime as long as possible
In the simplest direct communication routing protocol, each sensor node directly communicates with base station. Since the distance is large, it consumes the ....etc

random early detection matlab code implementation

Abstract

This section is meant as an introduction to the queuing at backbone networks, which often involves >100 megabit bandwidths, which requires a different approach than your ADSL modem at home.The normal behaviour of router queues on the Internet is called tail-drop. Tail-drop works by queueing up to a certain amount, then dropping all traffic that 'spills over'. This is very unfair, and also leads to retransmit synchronization. When retransmit synchronization occurs, the sudden burst of ....etc

Abstract

The migration to wireless network from wired net- work has been a global trend in the past few decades. The mobility and scalability brought by wireless network made it possible in many applications. Among all the contemporary wireless net- works, Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. On the contrary to traditional network architecture, MANET does not require a fixed network infrastructure; every single node works as both a transmitter and a receiver. Nodes communicate directly with each o ....etc
