ABSTRACT
This paper presents the architecture and protocols of SMesh,
a completely transparent wireless mesh system that offers
seamless, fast handoff, supporting VoIP and other real-time
application traffic for any unmodified 802.11 device. In
SMesh, the entire mesh network is seen by the mobile clients
as a single, omnipresent access point.
Fast handoff is achieved by ensuring that each client is
served by at least one access point at any time. Mobile
clients are handled by a single access point during stable
connectivity times. During handoff transitions, SMesh uses
more than one access point to handle the moving client. Ac-
cess points continuously monitor the connectivity quality of
any client in their range and efficiently share this informa-
