alternatively in a case where the network 10 is not a wireless network these links may be provided by electrical wires optical fiber cables or other physical connections between the nodes as shown in fig1 each of the nodes may be in direct communication with one or more other nodes and may be in indirect communication with one or more of the remaining nodes for example because of range limitations or otherwise the node 12 m u2212 3 is in direct communication with the nodes 12 m u2212 6 12 m and 12 m 1 and is in indirect communication with other nodes such as the nodes 12 m u2212 2 and 12 m u2212 5 through node 12 m u2212 6 the nodes 12 m u2212 6 12 m and 12 m 1 may be considered to be within the view of the node 12 m u2212 3 because they are in direct communication with the node 12 m u2212 3 however other nodes such as the nodes 12 m u2212 4 12 m u2212 1 and 12 m 4 are considered to be in indirect communication with the node 12 m u2212 3 because they can communicate with the node 12 m u2212 3 only through other nodes as shown in fig2 the node 12 which for example may be individually representative of the nodes shown in fig1 includes a computer 14 a memory 16 and a network transceiver 18 alternatively the computer 14 may be a processor or a computer data processor combination accordingly the word computer is used generically.
