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.

Abstract

In computer science, particle swarm optimization (PSO) is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality. PSO optimizes a problem by having a population of candidate solutions, here dubbedparticles, and moving these particles around in the search-space according to simple mathematical formulae over the particle's position and velocity. Each particle's movement is influenced by its local best known position and is also guided toward the b ....etc

ABSTRACT
Large scale dense Wireless Sensor Networks (WSNs) will be increasingly deployed in different classes of applications for accurate monitoring. Due to the high density of nodes in these networks, it is likely that redundant data will be detected by nearby nodes when sensing an event. Since energy conservation is a key issue in WSNs, data fusion and aggregation should be exploited in order to save energy. In this case, redundant data can be aggregated at intermediate nodes reducing the size and number of exch ....etc

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

Mobile Ad Hoc Networks are a wireless network which does not require any infrastructure support for transferring data from one node to another node .In these infrastructure networks, each node works as source, receiver and intermediate router. From this we can say that node can acts as host or router at different time period depending upon simulation time. If node wants to send the data it can act as a source and if node wants to receive the data it acts as receiver, if node has to transfer the data pac ....etc

Abstract

A MANET (Mobile Adhoc Network) is an infrastructure-less self configuring wireless networks of routers. It has potential applications in totally unpredictable and dynamic environment. Routing protocol used here is a form of reactive routing called AODV. AODV (Adhoc On Demand Distance Vector) routes based on demand. The major benefit of AODV is minimum connection setup delay and assignment of sequence numbers to destination to identify the latest route. The route updates are done by periodic beaconing. This network is susceptible to va ....etc

Abstract: Public key algorithms create a mechanism for sharing keys among large numbers of participants or entities in a complex information system.ECC is just mathematical equations to make it useful for security, it must be put in to algorithms like ECPVS(Elliptic curve Pintsov Vanstone Signatures) for digital signatures, ECDH(Elliptic curve Diffie-Hellman) for key agreement and ECIES(Elliptic curve Integrated Encryption Standard) for encryption.This works ensures more security on the network.
