The authors propose a new data-gathering mechanism for large-scale wireless sensor networks by introducing mobility into the network. A mobile data collector, for convenience called M-collector is a mobile robot or a vehicle equipped with a powerful transceiver and battery, and it gathers data from Polling Points (PPs) while moving through the field. Single M-collector ...

Mobile ad hoc networks are deployed in many new domestic and public applications, rising to new requirements in terms of performance and efficiency. However due to their nature, some usual network services as routing and security are not carried out as well as expected. Securing routing protocols is one of these challenging tasks, since security ...

Mobile Ad-hoc NETwork (MANET) is a network of mobile nodes that can communicate with each other without using any centralized control or fixed infrastructure. In this paper, analysis and performance of AODV, DSR, GRP and OLSR is done for 2Mbps data rate. The authors used OPNET Simulation tool to create a network containing 30 mobile ...

Smartphones are very popular now-a-days and also replacing the desktop and laptops because they have everything inside it. The chances of grabbing the users’ mobile phone are very high but only 2% of them are recovered due to which recovery of phones becomes a matter of chance. In this paper, the new tracking and data ...

Cellular devices have become integral part of everyone’s life and it will be, till dooms day in one way or the other. The broadband and Wi-Fi is the basic necessary ingredient of their life, it has multiple advantages but few disadvantages are such that it keeps their life at risk. People working in manufacturing units ...

The Internet of Things (IoTs) provides a virtual view, via the internet protocol, to a huge variety of real life objects, ranging from a car, to a teacup, to a building and to trees in a forest. Its appeal is the ubiquitous generalized access to the status and location of any “Thing” the authors may ...

Vehicles face growing security threats as they become increasingly connected with the external world. Hackers, researchers and car hobbyists have compromised security keys used by the Electronic Control Units (ECUs) on vehicles, modified ECU software and hacked wireless transmissions from vehicle key fobs and tire monitoring sensors, using low-cost commercially available tools. However, the most ...

Linear antenna arrays are used to optimize antenna array factor. 16 antenna arrays are used to achieve the results. Genetic algorithm is used for linear antenna array optimization by simultaneously optimizing two input parameters. It is performed on 16 element array. Reduction of SLL and nulls in desired directions are achieved in this paper. In ...

Cognitive radio is an emerging technology for the effective frequency utilization. The fixed spectrum allocation has resulted in spectrum holes. The cognitive radio solves the problem for unused spectrum by the mechanism of spectrum assignment. This paper proposes an efficient spectrum assignment by Markov scheduling, banker’s algorithm for deadlock avoidance and applying the graph coloring ...

With the increasing development of modern technology and Smartphone, smart way of living has turned out to be a major part in the present era of human life. Due to rapid growth in technology, Bluetooth has brought a revolutionary change. Bluetooth technology aims to exchange data wirelessly within a range of short distance by providing ...

Wireless Sensor Networks (WSNs) are been used in many applications such as: health care monitoring, environmental/earth sensing, industrial monitoring and data logging. But in order to reach their potential, researchers must find solution to some difficulties which are slowing down the wide spread use of these networks. These difficulties are inherent to their constrained specificities ...

To achieve security in wireless sensor networks, it is important to be able to encrypt and authenticate messages sent among sensor nodes. Keys for encryption and authentication purposes must be agreed upon by communicating nodes. Due to resource constraints, achieving such key agreement in wireless sensor networks is non-trivial. Many key agreement schemes used in ...
