System for Message Acknowledgement and Data Collection in Wireless Mesh Networks

摘要

A slave communication device includes a memory and a processor for operation within a wireless mesh network of communication devices including a control communication device. The memory stores a virtual routing identifier assigned to the slave communication device in response to increasing range from the control communication device. The processor, in response to receiving an initiation message from a control communication device, initiates data collection from said slave communication device synchronised relative to the start of the initiation message frame by, cumulatively setting bits in a first acknowledgement message in response to content of a second acknowledgement message received from another slave communication device. The first acknowledgement message being synchronized with start of the initiation message frame and the processor initiates communication of the first acknowledgement message to a destination in a time slot selected in response to the assigned virtual routing identifier.

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 slave communication device comprising:
a memory storing a virtual routing identifier assigned to said slave communication device in response to increasing range from a control communication device, said virtual routing identifier reflecting a distance of the slave communication device from said control communication device expressed by a number of routings; and a processor configured to, in response to receiving an initiation message from said control communication device, initiate data collection from said slave communication device synchronised relative to the start of the initiation message frame by,
cumulatively setting bits in a first acknowledgement message in response to content of a second acknowledgement message received from another slave communication device of said plurality of slave communication devices, said first acknowledgement message being synchronized with start of said initiation message frame andinitiating communication of said first acknowledgement message to a destination in a time slot selected in response to the assigned virtual routing identifier.
