Abstract
IN THIS THESE, THE QUALITY OF SERVICES QOS) OF AVERAGE DELAY, LOSSPROBABILITY, UTILIZATION,ADMISSION RATIO, AND THE NETWORK CAPACITY IN ADDIYION, EXTENSIVE SIMULATION PROGRAMS ARE EXECUTED TO INVESTIGATE THE POSSIBILITY OF TRANSMITTING MULTIMEDIA OVER ULTRA WIDEBAND NETWORKS. FURTHERMORE, COMPARISONS ARE MADE BETWEEN THE BEST PROPOSED PROTOCOL AND THE IEE802.15.3A PROTOCOI; WHICH IS THE IEEE STANDARD FOR ULTRA WIDEBAND MEDIUM ACCESS CONTROL PROTOCOL. THE BEST PROPOSED PRED PROTOCOL SHOWS BETTER PERFORMANCE IN BOTH SPARSE AND DENSE AND DENSE NETWORKS FOR REAI TRAFFIC TRANSMISSION.
UITRA WIDEBAND SYSTEM MODEL FOR NODES EQUIPPED WITH SMART ANTENNAS TECHNIQUE IS ESTIMATED. UWB CHANNEL CAPACITY IS BOUNDED BY THE EQUATION OF SIGNAL TO INTERFERENCE PLUS NOISE RATIO (SINR) WHICH IS AMENDED BY SMART ANTENNAS USAGE.
