Design issues of self-organizing broadband wireless networks

Design issues of self-organizing broadband wireless networks are examined i n this paper. As centralized solutions suffer from many inherent disadvanta ges, the responsibilities of organizing and controlling self-organizing net works should be fully distributed among wireless stations themselves. Wirel ess channel oriented adhoc multihop broadband (W-CHAMB) ideas that meet QoS demands for high performance services and realize statistical multiplexing of bursty traffic in a fully distributed and efficient manner are describe d in detail. The superiority of the performance of the W-CHAMB network can be seen in comparison with that of packet-oriented IEEE 802.11 WLAN. The hi dden station problem is completely resolved by means of the energy signal ( E-signal) solution. The performance gain of the E-signal solution over the RTS/CTS mechanism is evaluated through computer simulation, Finally, the ef fect of network connectivity on the traffic performance is discussed.
