In this paper, a Computational Intelligence (CI) based Simulated Annealing (SA) guided approach is used to construct the key stream. SA is a randomization technique for solving optimization problems. It is a procedure for finding good quality solutions to a large diversity of combinatorial optimization problems. This technique can assist to stay away from the ...

With the prolific growth in usage of smartphones across the spectrum of people in the society it becomes mandatory to handle and configure these devices effectively to achieve optimum results from it. This paper proposes a context sensitive model termed COSMOS (COntext Sensitive MOdel for Smartphones) for configuring the smartphones using multifactor analysis with the ...

Advances in Integrated Circuit (IC) processing allow for more microprocessor design options. As Chip Multi-Processor system (CMP) become the predominant topology for leading microprocessors, critical components of the system are now integrated on a single chip. This enables sharing of computation resources that was not previously possible. In addition the virtualization of these computation resources ...

GPS is one of the technologies that are used in a huge number of applications today. One of the applications is tracking the user’s vehicle and keeps regular monitoring on them. This tracking system can inform them the location and route travelled by vehicle, and that information can be observed from any other remote location. ...

Digital processing of speech signal and voice recognition algorithm is very important for fast and accurate automatic voice recognition technology. The voice is a signal of infinite information. A direct analysis and synthesizing the complex voice signal is due to too much information contained in the signal. Therefore, the digital signal processes such as Feature ...

The IEEE 802.11s Wireless Mesh Networks (WMN) is a new multi-hop technology increasing the coverage of IEEE 802.11 Wireless Network and providing Internet access. Recently, many researchers proposed several metric routing protocols for Wireless Mesh Networks (WMNs). Some metrics consider the interferences and other study the channel diversity of the distant links along the path ...

Control and Risk are the two parts of the coin. Risk management is the process of identifying vulnerabilities and threats to operating system resources to achieving business objectives and deciding what counter measures to take in reducing the lowest level of risk. The increased use of computer & communications system by IT industries has increased ...

In this paper, the authors propose time synchronized one-time-password scheme to provide secure wake up authentication. The main constraint of wireless sensor networks is their limited power resource that prevents the user from using radio transmission over the network to transfer the passwords. On the other hand computation power consumption is insignificant when compared to ...

Efficient implementation of block cipher is critical towards achieving high efficiency with good understandability.
