A Review on Tree Formation Technique in Wireless Sensor Network
Abstract: A typical task in wireless sensor network is to collect a data from sensor nodes towards sink. This paper shows various tree formation techniques used in the data gathering. In wireless sensor network, various data gathering techniques used that are hierarchical data gathering, chain based data gathering, tree based data gathering etc. This paper shows study on various tree formation techniques that can assist in data gathering. The data are …

A Threshold Based Scheme to Detect Black Hole Attack in DTN
Abstract: Security in DTN is a challenging task. Numbers of misbehaving attacks are present in the network. In this paper we focus on Black Hole attack with the problem of misbehaving and propose a solution based on the concept of threshold and validation. Each node maintains a local value called status of node. A node “status” is the delivery probability of nodes so doing, a misbehaving node is not chosen even …

Simulation of Different Routing Protocols using ONE Simulator in Delay Tolerant Network
Abstract: DTN (Delay Tolerance Network) is a network which is specially designed to handle long partitions and frequent delays occurring in previous wireless network. In DTN data is transmitted in store carry and forward manner. In this paper an attempt has been made to simulate different existing DTN routing protocols. For simulation ONE (Opportunistic Network Environment) simulator is used. ONE is free and easy to use simulator. Simulation is performed on …

A Reputation based Scheme to Detect a Black Hole Attack in MANET
Abstract: MANET is wireless network in which an end to end path is present between Network Security to MANET is wide problem. A black hole attack is an attack which drops the packets or provides wrong routing information to disturb routing process. In this paper we propose a new reputation based scheme to detect a black hole attack in MANET. In this scheme with the help of reputation of node we …

Speaker Identification using Hopfield Neural Network based Classifier
Abstract: The aim of this work is to enhance the performance of speaker identification using Hopfield neural network algorithm. Speech signals are collected from VALID Audio-Visual dataset and some speech signal pre-processing techniques are applied to process the speech to feed the Hopfield neural network algorithm. Filtering technique is applied to remove the noises from the speech signals. MFCC based standard speech feature extraction technique is used to extract the speech …

Contact-Based Routing to Improve Delivery Ratio in DTN
Abstract: Delay tolerant networks (DTNs) are a new development in network research field. DTNs are the networks where no end-to-end paths are present between nodes for a long period of time. DTNs are wireless networks where disconnections and delays are high. DTN works on the principle of store, carry, forward mechanism. A store, carry, forward mechanism is a mechanism in which when a node receives a packet then it stores in …

Flooding Techniques in Wireless Sensor Networks: A Review
Abstract: Intended for network-wide dissemination of commands, configurations and code binaries, flooding has been investigated extensively in wireless networks. However, little work has yet been done on low-duty-cycle wireless sensor networks in which nodes stay asleep most of time and wake up asynchronously. In this type of network, a broadcasting packet is rarely received by multiple nodes simultaneously, a unique constraining feature that makes existing solutions unsuitable. Combined with unreliable links, …
