Now-a-days, cloud computing is widely used to deliver services over the Internet for both technical and economic reasons. The number of cloud-based services has increased rapidly and strongly in the last years and so is increased the complexity of the infrastructures behind these services. To properly operate and manage such complex infrastructures effective and efficient ...

In recent years, huge requirements for broadband mobile wireless communications and the upcoming new wireless multimedia applications become the inspiration to the research of broadband wireless access technologies. The Long Term Evolution (LTE) system has been introduced by the Third Generation Partnership Project (3GPP) on the direction towards Fourth Generation (4G) mobile to conform 3GPP ...

As people have limited energy resources and computational power, data aggregation from multiple sensor nodes is done using simple methods such as averaging. WSN’s are usually unattended they are highly vulnerable to node compromising attacks. Thus making it necessary to ascertain trustworthiness of data and reputation of sensor nodes is crucial for WSN. Iterative Filtering ...

While the age-old concept of the network is foundational in virtually all areas of society, computer networks and protocols have forever changed the way humans will work, play and communicate. Forging powerfully into areas of the people lives that no one had expected, digital networking is further empowering users for the future. New protocols and ...

Web search engines such as Google, Yahoo and Microsoft Live Search are normally used to find certain data among huge amount of information in a negligible amount of time. Personalized search is a better way to improve the accuracy of web search and it has been attracting much more attention in recent times. Efficient personalized ...

When an oversized variety of beacons arrive in a very short time, vehicles are at risk of computation-based denial of service attacks that excessive signature verification exhausts their procedure resources. The authors tend to propose an economical broadcast authentication theme known as prediction-based authentication to not solely defend against computation-based DoS attacks, however additionally resist ...

Now-a-days, the IT world is going with use of virtualization technology in various aspects such as lab experiments, clustering, parallel processing, distributed system etc. in educational system. Educational systems are looking to virtualization to reduce cost and increase security concern solutions as a suitable infrastructure models. Relatively new to educational, the concept of virtualization is ...

Mobile Ad hoc NETwork (MANET) is composed of a collection of mobile nodes which are movable. Therefore, dynamic topology, unstable links, limited energy capacity and absence of fixed infrastructure are special features for MANET when compared to wired networks. MANET does not have centralized controllers, which makes it different from traditional wireless networks (cellular networks ...

Wireless Sensor Networks (WSNs) are intended for monitoring an environment by sensing it, then collecting data, processing it and finally transmitting it to final destination. These sensor nodes have some constraints due to their limited energy, storage capacity and computing power. Data are routed from one node to other using different routing protocols. There are ...

Software testing is a continuous process of development and maintenance. In maintenance phase, regression testing gets exercised with additional resources for performance. The prioritization of test cases helps to reduce the cost-time of regression testing. Hence, complete regression testing effectively. During software testing process many test suites can be generated in order to evaluate. In ...
