Recently, considerable research effort has been put into the direction of integrating the broadband wired ATM [1] and wireless technologies. In 1996 the ATM Forum approved a study group devoted to wireless ATM, WATM. WATM [2–4] aims to provide end-to-end ATM connectivity between mobile and stationary nodes. WATM can be viewed as a solution for next-generation personal communication networks, or a wireless extension of the B-ISDN networks, which will support guaranteed QoS integrated data transmission. WATM will combine the advantages of freedom of movement of wireless networks with the statistical multiplexing (flexible bandwidth allocation) and QoS guarantees supported by traditional...
