Abstract
A method and apparatus for generating connectivity is described. The method includes a server broadcasting a beacon including the server's address. The method further includes each client that receives the beacon rebroadcasting the beacon. The result is that each client receiving the beacon knows a way to reach the server.
Claims37
A method of wireless connectivity comprising:
- receiving a broadcast beacon at a client;
- the client deriving information from the beacon, the information allowing the client to identify all other clients in a multi-hop path from the client to a server;
- further comprising the client;
- storing every beacon received;
- designating one path identified by one beacon as the optimal path;
- setting a default gateway as identified in the optimal path;
- and
- rebroadcasting only the beacon representing the optimal path.

A method of wireless connectivity comprising:
- receiving a broadcast beacon at a client;
- the client deriving information from the beacon, the information allowing the client to identify all other clients in a multi-hop path from the client to a server;
- wherein the broadcast beacon includes a sequence number representing a current routing cycle.
A method of generating a routing path for a system including a server and a plurality of clients, the method comprising each client:
- receiving a beacon from one of the server or another client, wherein the beacon includes a sequence number representing a current routing cycle;
- the client deriving information from the beacon, the information allowing the client to identify all other clients in a multi-hop path from the client to a server;
- rebroadcasting one beacon received from an upstream node;
- and
- broadcasting a reverse beacon upstream, the reverse beacon being addressed to the known upstream node, the reverse beacon used by the server and each client to set up a routing table.
