In current wireless communication networks, bandwidth is a scarce resource and has to be exploited as efficiently as possible. Many multiple-access protocols have been suggested to access the available network bandwidth. We argue that most of these protocols are not suitable for our intended system1. Contention based multiple access protocols such as Aloha2, ISMA3,4, R-ISMA5,6 and PRMA7,8 are unsuitable due to their performance degradation under heavy loads. Source division multiple access protocols such as FDMA9, CDMA10 have the drawback that it is difficult to access multiple channels. In TDMA9 channels are sequential, multiple channels can be used to obtain more bandwidth. Furthermore, once a channel has been allocated to a mobile station the bandwidth is lost when that station has an inactive period.
