A Mobile Ad-hoc NETwork (MANET) consists of wireless mobile nodes. The communication between these mobile nodes is carried out without any centralized control. MANET is a self-organized and self-configurable network where the mobile nodes move arbitrarily. The mobile nodes can receive and forward packets as a router. In this paper, the authors compared the performance ...

Cloud computing promises to significantly change the way the authors use computers and access and store their personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the ...

Now-a-days, web services are widely used because of its features such as loosely couple, interoperable, reusable and so on. The Web Service Definition Language (WSDL) file is used to provide various functional and non-functional descriptions of a web service. The Simple Object Access Protocol (SOAP) is used to transfer messages between various web services in ...

With the speedy development and extensive use of Internet, information communication faces a huge challenge of protection. The authors require a protected and safe way to convey information. Encryption is a widespread system that is used for encrypting information. Except this for one it is very easy to gain the interest of the attackers because ...

A country which has its borders made by land faces major security threat from enemy infiltrations, with the help of ultra-modern techniques like concertina fencing, unmanned aerial vehicle and advanced imaging devices also fails to reduce the infiltration. This paper is to stop the infiltrators with the help of a simple mechatronic robot with GSM ...

In mobile ad hoc networks, data transmission is performed within an untrusted wireless environment. A wireless networks are more vulnerable to different types of attack than wired network. Various kinds of attack have been identified and corresponding has been proposed. Wormhole attack is one of the serious are attacks which forms a serious threat in ...

The Big-data refers to the large-scale distributed data processing applications that operate on unusually huge amounts of data. Google’s Map Reduce and Apache’s Map Reduce, its open-source implementation, are the defector software systems for large scale data applications. Study of the Map Reduce framework is that the framework produces a large amount of intermediate data. ...

Cloud computing refers to providing computing and communications-related services with the aid of remotely located, network-based resources without a user of such resources having to own these resources. The network in question typically, though not necessarily, is the Internet. The resources provisioned encompass a range of services including data, software, storage, security and so on. ...
