Montgomery Modular Algorithm of Radix Multiplication 1
G Suresh1 Assistant Professor, Dept. of ECE, Vidyaa Vikas College of Engineering and Technology, Tiruchengode, India
Abstract: Montgomery multiplication is an efficient method for implementation on general purpose computers and embedded microprocessors. It is the basic operation used in modular exponentiation which is required in the RSA public key cryptosystems. The algorithm uses simple divisions by a power of two instead of divisions by M which are used in a conventional modular operation and its implementation based on a fixed precision of the operands. In order to reduce the computation time by Radix-2 and Radix-4 algorithm and also to overcome the variable precision multiplication features although the number of partial product was reduced. The complexity of control and computational logic increased substantially at the same time. The approach was able to process an n-bit precision multiplication in approximately n clock cycles to simulate by Xilinx 12.3 tool using VHDL language.

Enhancement in Leach Protocol for Large Scale Wireless Sensor Networks 1
T Rajkumar1 Assistant Professor, Vidyaa Vikas College of Engineering and Technology, Tiruchengode, India
Abstract: As the use of wireless sensor networks (WSNs) has grown enormously in the past few decades, the need of scalable & energy efficient routing and data aggregation protocol for large scale deployments has also risen. LEACH is a hierarchical clustering protocol that provides an elegant solution for such protocols. One deficiency that affects the performance of the protocol is existence of very large and very small clusters in the network at the same time. This leads to the decrease in lifetime of WSNs. In this paper, the proposed and analysed a new energy efficient clusters protocol (Improved FZLEACH) that eliminates the above problem by forming Far-Zone. Far-Zone is a group of sensor nodes which are placed at locations where their energies are less than a threshold. The communication between nodes and Sink is based on the energy consumption and the minimum distance. The communicating nodes only will be in active and the remaining nodes will be in sleep mode, to this sleep scheduling algorithm has been used. The simulation results and analysis show that proposed Improved FZ-LEACH algorithm outperforms LEACH in terms of energy consumption and network lifetime.
