1. A method of distributing data in a network comprising a plurality of mobile nodes and at least a first fixed node, wherein at least a portion of the network for communicating with said mobile nodes is wireless, said method comprising the steps of:
- (1) transmitting data via said wireless portion of said network from said fixed node to at least a first of said mobile nodes that is within wireless transmission range of said fixed node; and
(2) transmitting said data from said first mobile node to a second of said mobile nodes responsive to said first mobile node coming within wireless transmission range of said second mobile node.

10. A method of distributing data in a network comprising a plurality of mobile nodes and at least a first fixed node, wherein at least a portion of the network for communicating with said mobile nodes is wireless, said method comprising the steps of:
-
(1) said mobile nodes issuing requests via said wireless portion of said network for data from said fixed node;
(2) responsive to receipt of said requests, said fixed node transmitting said data via said wireless portion of said network to said mobile nodes from which it receives said requests;
(3) if a mobile node does not receive said data requested in step (1) from said fixed node, said mobile node issuing a request for said data from other mobile nodes; and
(4) if another mobile node receives said request issued in step (3) and has said requested data, said another mobile node transmitting said requested data to said requesting mobile node. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method of distributing data in a network comprising a plurality of mobile nodes and at least a first fixed node, wherein at least a portion of the network for communicating with said mobile nodes is wireless, said method comprising the steps of:
-
(1) said mobile nodes maintaining a list of data items that are to be synchronized to said data of first fixed node corresponding to said data items;
(2) if a mobile node is within wireless transmission range of said first fixed node, synchronizing said data corresponding to said data items at said mobile node with said data corresponding to said data items at said first fixed node;
7(3) if a mobile node is not within wireless transmission range of said first fixed node and is within wireless transmission range of another mobile node, synchronizing said data corresponding to said data categories at said mobile node with said data corresponding to said data items said another mobile node. - View Dependent Claims (18)

19. A mobile network node for communicating with a server node as well as other mobile network nodes via a wireless portion of a network comprising:
-
a memory for storing data;
a radio for wirelessly communicating via said wireless portion of said network;
a first circuit for synchronizing data stored in said memory with corresponding data stored in said first server node via said radio;
a second circuit for synchronizing data stored in said memory with corresponding data stored in another mobile node if said mobile node cannot communicate with said server node, but can communicate with another mobile network node. - View Dependent Claims (20)
