In recent trends, android smartphones are rapidly in use by a number of users because of its user friendly and open source architecture. There are millions of android applications are available in the open market place. But we cannot trust most of the apps, which may steal the user privacy content or any confidential data. However, some works have studied mobile phones, multimedia securities and also...
Optimal channel sensing and allocation schemes enable Cognitive Radios (CR) to identify and opportunistically transmit on under-utilized radio frequencies. Intelligent way of channel sensing strategies reflected directly to the major performance factors like end-to-end delay, interference, packet loss ratio and energy consumption. Since most of the CR devices are low power handheld devices, we need...
MANETS are randomly distributed self-configurable networks used in an ad-hoc fashion. Due to its increasing network data, load balancing becomes an unmanageable aspect in these networks. Various load balancing techniques though have been proposed; Random, Scheduling and Evolutionary load balancing models differentiates and allocates the load into different levels, providing a maximum network manageable...
Peer-to-Peer Network consisting of nodes with limited power that are deployed to gather useful information from the field. In P2P it is critical to collect the information in an efficient manner, sometimes Single point failure can be occurred, and also congestion can be occurred in the network. In order to avoid those problems we proposed a new technique called Bio-Inspired mechanism for caching....
Inefficient use of the spectrum led to the development of cognitive radio network, especially in clustered environment, channel selection is considered as a main factor. If the channel selection is not efficient then it may lead to propagation delay. The propagation delay is directly proportional to channel selection scheme inside the cluster. Various channel selection techniques such as Aloha, Markov...
As the use of the web is greatly increased so as the need for effective web service selection and retrieval techniques. So many good algorithms have been developed for web service selection problem. The need for effective web service clustering technique is also came forward, which will help the users to search within their needed clusters, that will reflect different tradeoffs such as price , quality...
Sensing optimal idle channel for future transmission is the hot research topic in Cognitive radio (CR) network environment. CR Network performance greatly depends upon the waiting time of the Cognitive User (CU) for getting free channel from licensed band. Probability of available free channel will be less when arrival rate of primary user to their allocated licensed band is high. So the effective...
