As computer technologies are highly emerged in today's world, leading organizations have digitalized their maximum data transferred in their organization. These leads to digital data maintenance issue as well as issue of retaining the knowledgeable data, which is considered as organization intellectual asset. Organizations are taking higher steps to build knowledge repositories to retain their knowledgeable data on centralized shared storages. The importance of maintaining knowledge repositories to preserve the intellectual capitals has made the institutions to plunge in the ease of creating knowledge repositories for holding institutional intellectual assets. This research contains a novel approach of creating an environment to build knowledge repository for institutions, which provides a mode of capturing the externalized knowledge transferred in the institutions by the stack holders.Keywords

Securing Mobile ad hoc net work is a challenging task due to the lack of trust among nodes. In this paper we analysis various trust models for Mobile ad hoc network and then propose a trust evaluation model for mobile ad hoc network which estimating trust level of supplicant nodes by Evaluating and analysis node behavior. This model also designed to detect compromised nodes inside the environment and to isolating the compromised and misbehavior nodes from the network. This model also tested through introducing misbehavior nodes and compromised nodes into the environment and the result shows that the model is highly effective in detecting misbehavior node and compromised nodes over various other security models for Mobile ad hoc network.Keywords

Mobile ad-hoc network (MANET) is collection of wireless mobile hosts forming a temporary network with out the aid of any standalone infra structure or centralized administration. Mobile ad-hoc network have attributes such as wireless connection continuous changing topology, distributed operation and ease of deployment. Ad-hoc network has emerged as an important trend of future wireless systems that will provide ubiquitous wireless access. In this research we study that performance optimization challenges of ad-hoc network and cross layer processing to improve its performance. We implemented cross layer processing between physical (PHY), medium access control (MAC) and network (NET) layers using network simulator NS-2. The MAC layer adaptively selects a transmition data rate based on the channel signal strength information from the physical layer. The MAC layer utilization is sent to DSR routing protocol as a congestion aware routing metric for optimal route discovery.Keywords

This paper is concerned towards providing trust based authentication key distribution system for mobile ad hoc network (MANET). Traditional authentication key distribution methods cannot be able to adopt for securing the MANET due to infrastructure less nature and lack of trust among nodes. We propose an authentication key distribution scheme for MANET which authenticates a node as well as provide a trust chain among nodes which enables secured and reliable key distribution. This paper also focuses on enhancing co-operation between nodes through trust chain.Keywords

RFID unlike barcodes enables simultaneous detection of multiple distant and non-line of sight objects. These characteristics make them exceptional and broaden its scope and utility of RFID systems. Signal transmissions from multiple tags result in tag collisions or confusion causing increase in identification delay, communication overhead and power consumption. In general conventional protocols, utilisation of time slots are in rise, when the tag population increases exponentially. The protocols suggested in recent years follow a “win one – loose other agreement”. Though BT, QT, variants of QT, AQS and ABS who show superiority in minimizing collision, identification delay and transmitting bits, they are no longer memoryless. Cluster Adaptive Memoryless Protocol (CAMP) proposed in this paper takes account of all requirements of a good collision protocol. The grouping procedure and tree construction adopted makes the algorithm to stand apart.Keywords

Recently, vehicular networks have begun to attract much attention in industry as well as academia. The IEEE 802.11p is known as Wireless Access in Vehicular Environment (WAVE) to provide the vehicle-to-vehicle and vehicle-to-infrastructure communications. The objective of this paper is to give a study and compare the protocols IEEE 802.11p with IEEE 802.11a. NS2 simulation framework has been developed to evaluate the performance of wireless access technologies and study the packet loss occurred during transmission. Also, this framework is developed to meet the requirements for vehicle to infrastructure communications and it is extended to vehicle to vehicle communications for vehicular ad hoc networks.Keywords

Mobile Ad-hoc Networks (MANETS) operate in highly dynamic environments with limited resources. Due to ever-changing network topology and unreliable wireless channels the performance of the Ad-hoc network is poor. A key challenge is to create a mechanism that can provide good delivery performance and high quality of service in network. The key components of the approach include a cross layer design to improve information sharing between the different protocol layers. In order to improve the performance of MANET, it is planned to implement the cross-layer mechanism from data link layer to the routing layer which can improve the performance of mobile Ad-hoc Network (MANET) routing protocols. It involves allowing the MAC layer of mobile node to learn of the route layer to MAC address mapping of nodes from destination that it receives. This mechanism may improve the reliable transport using the TCP protocol. Simulation of this work is carried out in NS2.Keywords
