Wireless EnergymeterEssay Preview: Wireless EnergymeterReport this essayINTRODUCTIONThe present system handled for the calculation of electricity bill by the electricity bill by the electricity board takes more time. On the other hand man power involved in this process is more, this is because the persons taking readings has to travel to various to collect each consumers energy meter readings eliminated by substituting any remote systems and by wireless communication.
In this project we use remote calculation systems. The data can be transmitted through different means. Some of them are IR data communications, RF data communication etc out of these, RF communication find various advantages over other communication systems. Although there are many successful application using RF waves, the wireless communication find wide application using RF waves. Hence in the project we use RF data communication for data transfer which can communicate well and maintain consistent performance even for long distances, providing better data communication in all conditions.
SYNOPSISNowadays most of the calculations are being done and records are maintained using computer. But one of the most familiar calculations, the electric tariff calculation is manually carried out. This takes more time for having the readings and for calculating the cost. Also the record maintenance is very expensive and difficult. This problem is overcome by transmitting digital data obtained from the energy meter through the transmitter from the transmission block and these data are received in the control block and the calculations are made and recorded using a PC.
Hence the major involved in electric tariff calculation can be solved by implementing this project we can minimize man power thereby labour cost. Mainly the time is saved.

RELEASE NOTES
1,7 This release is part of the Software. This release provides cryptographic data and functions for the ARM. ARM-1 has been developed in conjunction with the ARM (ASIC & APIC) platform and the AHC. This means that any instruction, regardless of source code, can be defined and executed by this platform through the ARM. Asymmetric cryptography allows the use of two distinct encryption systems. This code is used to establish a symmetric relationship, as opposed to a symmetric password, which is often used by encryption methods. The ARM encrypts a file with a specified length, then provides a private key. For any file with a long length, the new encryption key is sent to the server. In addition, the server then decrypts the file and makes the server available to data sharing. If an attacker wants to create an access to the server, all the parameters of the file are then used to generate a key that the server recognizes as the security key for the file. A shared key is used to authenticate a remote attacker, which is typically known as a root certificate or root server. This means that only a unique code is used to authenticate an attacker and a unique key is used locally, to sign an authorization token from the server on the server. If the server knows the password of your file, then the attacker can brute-force it into a key which requires a server token to decrypt it. If an access key is used locally, all of the parameters are discarded.This version also provides support for OpenSSL 2 or higher. This implementation has no support for TLS (TLS 2.0 or above). A special version of this release is available for download from https://github.com/amd-server/OpenSSL/blob/master/lib/openssl-2-2.0.tar.gz, for a complete overview of OpenSSL 2.0 and other features.
