Advent of PHY and MAC Layer Operations in Wireless and Local Personal Area Network

Abstract
Carrier sense multiple access with collision avoidance (CSMA-CA) algorithm is implemented on AT86RF230 Trans-receiver, which is done in Physical layer. As the number of nodes is increased, power efficiency of CSMA-CA algorithm is decreased. Power efficiency is improved in terms of Throughput and Block acknowledgement. Fragmentation increases the reliability of correct transmission. Both high and low data rate can be supported through multirate design. Data Scrambler and Data Whitener is implemented. Finally the transmitted and received information is analyzed using Analyzer.
