System for wireless mesh network communication

摘要

A general wireless mesh network of communication devices with packet message transmission, especially for telemetry and automation, includes at least a single control communication device and a set of slave communication devices. The control communication device searches in the network and assigns a virtual routing number to each slave communication device. The virtual routing number reflects a distance of the slave communication device from the control communication device, expressed by the number of routings, and is stored in the slave communication device. The slave communication device, for further routing of packets in the mesh network, uses time slots assigned according to the difference between said virtual routing number and the virtual routing number of the sender of a received packet. Packet routing is based on successive flooding of the virtual routing structure and time division multiplexing.

1. In a wireless mesh network of communication devices using packet message transmission including a plurality of slave communication devices and at least one control communication device, a system comprising:
a control communication device configured to,
iteratively send:
first messages to determine a first set of slave communication devices within range of the control communication device, andsecond messages to determine a second set of slave communication devices within range of the determined first set, andin response to iteratively sending first messages and second messages, assign an increasing virtual routing identifier to a slave communication device with increasing range from the control communication device, the virtual routing identifier reflecting a distance of the slave communication device from the control communication device expressed by a number of routings.
