  • Method and system for distributed roaming services for mobile users on wireless mesh networks
    Patent number: 7711361
    Abstract: A method and system for distributed roaming in a wireless mesh network are disclosed. Cells are able to track and predict a users movement throughout the network. The user's roaming profile is forwarded to predicted future cells before the user actually enters those cells. When the user enters a new cell, roaming is completed without communication to any other cells. Thus, handoff time is reduced and users may more seamlessly move throughout the network coverage area.
