  The computer network is telecommunication channel to share data among different entities. It is a distributed system through which the data is transmitted and received over internet. The network should be reliable, secure and having good performance in terms of speed and throughput. The WLAN technology enables the wireless connection in frequent manner rather than wired connection within campus or building. The technology uses the radio frequency to send and receive data in air. The WLAN standard is developed by IEEE and common standard is IEEE 802.11 and IEEE 802.11x as family with different specifications. The IEEE 802.11 standard specifies an air interface between a base station and wireless client or two wireless clients. The study is discusses the different computer networks as LAN, MAN and WAN, Global communication coverage and different 802.xx standards.

  Smart grid is a distributed automated network which uses two way communication and energy flow to consumers at minimum disturbance. The grid, refers to the electric grid, a network of substations, transmission lines, transformers and meters that deliver electricity from the power plant to our business and home. Power generation and distribution are the key aspects in the progress and development of our societies. The communication network and infrastructure are the main part of the smart grid. The smart grid reliability is one of the important features which depend on the data received from distribution side of the network. Different challenges are faced in the conversion of conventional grid to smart grid and still research is going on the different issues of smart grid such as secured communication, network enhancement and reliability. Home energy management depends on the utilization of the electricity on consumer side. The smart grids follow the renewable energy generation, latest sensing and communication technology, smart metering and power management. Wireless sensor networks and wireless communication technologies also play very important role in smart grid communication. WSN has been proved promising solution for energy efficient, reliable, seamless and low cost control and monitoring in smart grid. The research is study based on the study of smart grid, smart grid system and different communication technologies.

  This research study proposes a novel architecture for a memory based pipelined fast fourier transform for a complex-valued signals which is based on radix-2 Decimation-In-Frequency (DIF) algorithm. A method of stage partition for a Complex Fast Fourier Transform (CFFT) to minimize the computation clock cycles and maximize the utilization of the Processing Element (PE) is proposed. In addition to this the CFFT architecture can also support more PEs in two dimensions as well. As compared to the previous research, the suggested CFFT processors have fewer computation cycles and lower hardware usage. ISE Xilinx 12.2 tool in verilog language has been utilized for designing and simulation.

  Background and Objectives: Wilt of tomato caused by Fusarium oxysporum f. sp. lycopersici (Sacc.) W., is one of the most economically important disease of tomato occurring world-wide. In the present study, the mycoparasitism inhibitory affects of three Trichoderma species (T. viride, T. harzianum and T. koningi) on the growth of the causal agent of tomato Fusarium wilt (Fusarium oxysporum f.sp. lycopersici) were investigated by dual culture under in vitro conditions. Materials and Methods: Already identified Trichoderma species viz. Trichoderma harzianum, Trichoderma viride and Trichoderma koningii were taken for the present experiment used to check their relative viability against Fusarium oxysporum f. sp. lycoperisci by dual culture techniques. All the isolates of Trichoderma were evaluated for the growth pattern on five different media along with different temperature and pH range. Results: Trichoderma harzianum inhibited maximum radial growth (75.7%) of Fusarium oxysporum f. sp. lycopersici pathogen during the experiment followed T. viride. During the same study all these Trichoderma isolates were evaluated on five different solid media for assessing growth and sporulation and the maximum radial growth of Trichoderma harzianum were found in Potato Dextrose agar whereas the lowest growth was observed in Trichoderma selective medium. Similarly, excellent growth of Trichoderma spp. was found at temperature range of 25±2°C, while 5.0-7.0 pH was found the most favourable for the growth and sporulation of Trichoderma spp. Conclusion: Out of all the three species of Trichoderma, the maximum inhibition of the test pathogen was furnished by Trichoderma harzianum. On the basis of present study the fungal bioagents, might be exploited for future plant disease management programs (DMP) to save environmental risk.
