Handoff method in a wireless packet network avoiding loss or delay of packets
WO 2002073988 A3
Abstract
Mobile nodes receive services from stationary base nodes in a wireless packet network. The stationary nodes are associated in groups by which packets are forwarded to and from the mobile nodes. Each group provides services to mobiles within a geographical area. Each node in a group can transmit all or parts of an incoming or outgoing packet for a mobile node moving within the area. Parts of packets and acknowledgements are generally distributed throughout the group.
