Abstract: A cognitive radio (CR) network is a multiuser system. Cognitive users(CU) compete for limited resources in an opportunistic manner by interacting with each other for access to the available resources. In CR networks‚ proper power controlling is important to ensure efficient operation of both primary and cognitive users. In this paper‚ an algorithm is used to dynamically control transmission power‚ which is capable of achieving reasonably good solutions fast enough in order to guarantee

RELAY A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically‚ but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits)‚ or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits‚ repeating the signal coming in from one circuit

A Technical Comparison of 802.11n to 802.11g A Technical Comparison of 802.11n to 802.11g Abstract 802.11n was developed to address issues of distance and speed. These were issues with wireless g and especially big issues with legacy devices that were used previously. Wireless N devices allow for a wider range by using multiple-input multiple-out and multiplexing allowing more data to be sent at a given time than before in previous a/g devices. It also allows for better communication between

1. INTRODUCTION 1.1WIRELESS ELECTRONIC NOTICE BOARD USING R.F:- Data Security is primary concern for every communication system. There are many ways to provide security data that is being communicated. However‚ what if the security is assured irrespective of the hackers are from the noise. This Project describes a design of effective security for data communication by designing standard algorithm for encryption and decryption. R.F. is a PAN technology based on the IEEE 802.15.4 standard.

Audion: A New Receiver for Wireless Telegraphy‚ from the Scientific American Supplement. The original Audion was capable of slightly amplifying received signals‚ but at this stage could not be used for more advanced applications‚ such as radio transmitters. The inefficient design of the original Audion meant it was initially of little value to radio‚ and due to its high cost and short life it was rarely used. In fact‚ in the 1909 edition of Operator’s Wireless Telegraph and Telephone Hand-book‚ Victor
