Abstract :
Increasing user demand for more bandwidth over wireless communications has motivated a new challenge to utilize the benefits of wireless ATM technology. This paper focuses on how to provide IP services to a mobile user over wireless ATM networks. It seems to be able to support the mobility by combining the existing schemes developed by the IETF and ATM Forum such as Mobile IP, IP over ATM, Next Hop Resolution Protocol (NHRP), mobile PNNI, and LR (location register) schemes. They may be so called “Mobile IP over ATM” or “IP over WATM”. However, these naive combinations of existing schemes may result in shortcomings such as inefficiency, duplication of functions and waste of resources. Thus, a new efficient scheme called mobile NHRP is proposed to provide IP mobility support over wireless ATM networks. Also, the fault tolerant routing with mobile NHRP is described
