Performance Analysis of Cognitive Radio Networks for Resource Sharing

All secondary users are not only opportunist but may be used as co-operative

Produktbeschreibung

In cognitive radio system, secondary users are queued when primary users are utilizing its own channel. In that case secondary transmitters are idle and waiting for that channel to be freed. If so, why not use that idle secondary transmitter for primary users as helping hands by transmitting primary's data. This book explore the scarcity and management of current spectrum issue and proper management in three distinct methodologies. Firstly, Field surveying of spectrum within the range of 0.1 GHz to 3 GHz is done for finding white space. Secondly, white space is managed using user friendly graphical environment programmed in Matlab. Finally, performance is increased by reducing waiting delay in queue for secondary users. Sharing 50% of primary users' data by secondary transmitter, performance is increased up to 41% based on traffic load of incoming data on server and better on high traffic. Wireless Regional Area Network IEEE 802.22 parameters with data rate 24 Mbps is used for simulation in Matlab.
