    Wireless Sensor Networks: A Study on Congestion Routing Algorithms

    Data's generated in Wireless Sensor Networks may not all alike, some data's are more important than other data's and they may have different delivery requirements. If congestion occurs in the Wireless Network, some or more important data's may be dropped. But in the authors' project they handle this problem by...

    Analysis and Study of Denial of Service Attacks in Wireless Mobile Jammers

    Nature of the medium in wireless networks makes it easy for an adversary to launch a Wireless Denial of Service (WDoS) attack. Recent studies, demonstrate that such attacks can be very easily accomplished using off-the shelf equipment. To give a simple example, a malicious node can continually transmit a radio...

    QoS Based on Ant Colony Routing for Wireless Sensor Networks

    The Wireless Sensor Networks (WSNs) are composed of nodes communicating over a wireless media, without the need for physical infrastructure. In this type of topology, all nodes cooperate to ensure the proper management of the network (control, routing, etc.). Fully distributed nature of such networks is the problem of performance...

    Performance Modeling of Distributed Load Balancing Algorithm Using Neural Networks

    This paper presents a new approach that uses neural networks to predict the performance of a number of dynamic decentralized load balancing strategies. A distributed multicomputer system using any distributed load balancing strategy is represented by a unified analytical queuing model. A large simulation data set is used to train...
