1. A network comprising:

  • at least one fixed gateway node, the fixed gateway node being in communication with the Internet; and

    a plurality of wireless nodes, each of the wireless nodes including wireless transceivers, each of the wireless nodes includes an upstream routing table and a downstream routing table, each of the wireless nodes being configured to use its upstream and downstream routing tables to make routing decisions, some of the wireless nodes being mobile wireless nodes, some of the mobile wireless nodes being configured to act as a relay for other wireless nodes that cannot directly access the at least one fixed gateway node;

    wherein at least one first wireless node has an upstream routing table listing a second node and a corresponding hop count relative to the at least one fixed gateway node for the second node, the corresponding hop count for the second node being lower than a hop count for the first wireless node, and wherein at least one third wireless node has a downstream routing table listing at least one fourth wireless node with a corresponding hop count relative to the at least one fixed gateway node, the corresponding hop count for the fourth wireless node being higher than the hop count for the third wireless node.
