This paper presents a novel cascaded multilevel inverter structure with reduced devices. This structure is termed as sequential switch cascaded multilevel inverter. The basic asymmetrical hybrid circuit is described and is capable of generating 17 voltage levels. The various modes of deriving 17 levels are explained and the proposed topology is compared with existing topologies in various aspects. Neural network controller can be used to generate the gating pulses. The algorithm can be trained online by using back propagation algorithm and also an algorithm to determine the number of levels, maximum voltage ratings and power loss is explained. The simulation can be done by MATLAB Simulink.
Online testing of processors integrated in WSN nodes operates on battery, and battery duration determine the lifetime of the system, this paper proposes an new clustering Embedded systems less resource utilization. Clustering is a new approach to efficiently utilize the energy of sensor nodes, this approach helps to reduce the network traffic as well as resources utilization, we propose a new energy efficient and reliable clustering algorithm called ACTOR DIRECTED CLUSTERING PROTOCOL (ADCP) that increases the life time of network and our simulation results in efficiently deliver data to an actor node with minimum delay, that helps for taking a quick action and control the attack in its initial stage. Actor Directed Clustering protocol (ADCP) algorithm is used for election and maintaining network traffic clustering Technique is modified for WSN, Low power ratio can be achieved. A link life time prediction routing algorithm can be added with the ADCP protocol. Simulation results show that energy savings at processor level are up to 40 % percent.
RC4 encryption algorithm [3,12,16] was examined based on the text to be encrypted and the chosen key. It is a symmetric key algorithm and uses stream cipher i.e. data is being encrypted bit by bit. The same algorithm is used for both encryption and decryption. The data stream is XORed with the generated key sequence and the key stream is completely independent of the plaintext used. The weakness of the algorithm has been found out and is being rectified. We proposed a modification in RC4 algorithm that would result in saving the memory space and also augment the performance by reducing the time. The proposed algorithm explains that we can have the key as an image so that we can compress it and store. Hence the algorithm yields better results in hardware also.
This paper fully based on the Interline Power Flow Controller(IPFC) with optimal power flow in Transmission System, because the flow of electricity through the transmission lines can be effectively controlled by using IPFC. This paper contains IPFC is developed for four bus system. The performance of IPFC
