1. A linking process for establishing a sequence of linked nodes at a head-node of an array of nodes, each of said nodes being equipped with a wireless communication device of limited range, the linking process comprising the steps of:

  • transmitting packets including a unique identification from each of said nodes, each said communication device modeling a phase-variable oscillator i such that when phase θ

    i =1, the ith oscillator "fires", transmitting the packet, and θ

    i jumps back to zero and, on receiving a packet, changes phase according to a phase-response curve, thereby setting up a wave pattern of transmission of packets;

    updating a local map at each node based on received packets from adjacent nodes;

    periodically transmitting from each node a current local map; and

    compiling, at the head node, a network map of the sequence of the nodes in the network from the local maps received.
