Abstract
A wireless mesh communication protocol that dynamically assigns communication time-slots and frequencies to mesh nodes. A first node is established as a PC that sequentially polls other nodes. A second node responds at a predetermined time with information that includes database records, and then a third node responds similarly. The second node is then established as the PC and the first node is polled during dynamically allocated time-slots and on a frequency that depend on the second node's database records. The third node is then established as a PC and acts similarly. In both cases the first node responds by sending information and data records. The first node is then re-established as the PC. The first node then polls the second and third nodes at times and frequencies that depend on the first node's database records.
