MACRO MOBILITY IN COMMUNICATION NETWORKS

摘要

Mobile nodes receive services from stationary nodes in a communications network. Primary base nodes have associated groups of peer nodes that are able to transmit all or parts of incoming packets to mobile nodes which remain within geographical zones determined by the groups. A packet addressed to a mobile node is sent from a correspondent node to a care-of node. The packet is forwarded from the care-of node to a group of peer nodes associated with the care-of-node. All or parts of the packet are forwarded from the care-of node and the peer nodes to the mobile node according to location of the mobile node. A group of peer nodes is preferably defined for substantially each node in the network according to expected geographical movement of the mobile nodes.
