Mobile Ad Hoc Network (MANET) is a collection of independent self communicating devices under different movement patterns. Mobility is one of the factors influencing routing process and its performance in these networks. As the network is decentralized, each node adopts different mobility pattern. Frequent changes in position of the nodes have direct impact over network efficiency and its performance...
In commercial wireless communication systems, higher data rates and reliable communication is required. The challenge in system design is the multipath fading which results in weak signal strength at the receiver, this increases the Bit Error Rate (BER) of Communication Systems. Employing multiple antennas is used to get reliable performance through diversity and achievable higher data rate through...
Ad hoc networking provides movable devices to establish communication independent of a main infrastructure. However, the fact that there is no main infrastructure and that the devices can move randomly gives rise to various kind of problems, such as routing and security. In this system, path routing and protocol selection are the primary strategies to design any wireless network. In mobile Adhoc network...
This paper deals with performance analysis such as outage probability and transmission capacity of Multiple Input Multiple Output (MIMO) ad-hoc network with channel state information at transmitter (CSIT). Network formed by scattering a fixed and finite number of nodes in a given area. This type of nodal arrangement is a Binomial point process (BPP) where area or volume of deployment is finite and...
Advanced Encryption Standard (AES) is the one of the successful algorithm in the cryptography. AES S-Box with minimal power consumption gives a typical challenge in today's research environment. In AES, S-Box consume more power when compare to the other AES operation. S-Box is implemented using the composite field which has the different arithmetic properties. In S-box, Algebraic Normal Form (ANF)...
Cloud computing has emerged as one of the most influential paradigms in the IT industry. In this, new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Several schemes employing attribute-based encryption (ABE) have been proposed for access control of outsourced data in cloud computing...
This paper presents the design and chararacterization of Radio Frequency (RF) Micro Electro Mechanical System (MEMS) based switchable low pass filter. The proposed design of the switchable filter is used in space applications for frequency switchability where electromagnetic spectrum can be effectively utilized. In this paper, RF MEMS Switches are used to achieve tunability between two frequencies...
Vehicle license plate identification system is an image-processing technology used to identify vehicles by their license plates. This technology is used in various security and traffic applications. This data is also used for enforcement, data collection, and can be used to keep a time record on the entry or exit of vehicles for automatic payment calculations. The significant advantage of this system...
This paper presents a decentralized control technique for multivariable processes. Both the steady-state and transient information of the process transfer function are investigated. A new interaction measurement, relative normalized gain array, is proposed for evaluating control-loop interactions. Consequently, a new loop pairing criterion based on the relative normalized gain array is proposed for...
This paper describes the application of modified Particle Swarm Optimization (PSO) called Fitness Distance Ratio PSO (FDR PSO) algorithm to determine the optimal power dispatch of the Independent Power Producers (IPP) in deregulated environment. Generally the power producers must respond quickly to the changes in load and wheeling transactions. During this process, the ramping cost must be incurred...
