Mobile networks are ever expanding and have come to take up the center stage in communication industry. Basically a MANET is used to communicate using wireless links with mobile devices forming a temporary network. This kind of network changes dynamically and contains a self-organized infrastructure-less topology. The motive to look for the security in Mobile ...

Mobile Ad-hoc NETworks (MANETs) routing attacks are considered as a serious issue. However, in the presence of malicious nodes, the networks are affected by various kinds of attacks. The malicious node(s) can attack a MANET in different ways, such as sending fake messages several times; fake routing information and advertising fake links to disrupt routing ...

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 ...

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 ...

Wireless networks have long suffered from congestion. It occurs when source node transmits the data at a rate greater than that of a network device can accommodate. It causes the buffer on such devices to fill up and possibly overflow. It results in loss of packets. Most of the routing protocols which are currently in ...

In this paper, the authors present a hardware and software platform for wireless sensing applications. The hardware kit consists of two types of self-contained, expandable sensor nodes, as well as, a multipurpose base station and programmer, a cascadable charger and sensor modules. The software kit consists of an Integrated Development Environment (IDE) for application programming ...

A Vehicular Ad hoc NETwork or VANET is a novel approach of intelligent transportation system technology which has received significant attention recently. Routing in VANETs is a challenging task due to network partitioning, high vehicular speed and city environment characteristics. These characteristics results in degraded performance in traditional routing protocols. Traditional routing protocols, addressing the ...

In this paper, the authors were to investigate the application of Geographic Information System (GIS) in property valuation. The paper adopted descriptive research design to investigate the relationship between value of land and the factors influencing it. A population of 400 land parcels was used with a sample size of 100 parcels of land. Data ...

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 ...

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 ...

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 ...
