BROADCAST RETRANSMISSION

摘要

A wireless communication device configured to receive a first data packet identified as being of a broadcast packet type, the first packet comprising a first mesh network data packet that comprises a payload and a first lifetime value. A portion of the first packet may be compared against a record of mesh network data packets previously received by the device. If the record indicates that the first packet has not been previously received by the device and if the first lifetime value of the first packet is not equal to a predetermined threshold value, then form a second mesh network data packet that is unaltered from the first packet except that the first lifetime value is changed to indicate that the first packet has been received. The second packet may be transmitted within a second data packet that is identified as being of the broadcast packet type.

主权项

1. A wireless communication device capable of operating according to a wireless communications protocol, which defines a broadcast packet type, and capable of communicating in a mesh network, the wireless communication device being configured to:
receive a first data packet identified as being of the broadcast packet type, the first data packet comprising a first mesh network data packet that comprises a payload and a first lifetime value; compare at least a portion of the first mesh network data packet against a record of mesh network data packets previously received by the wireless communication device; and if the record indicates that the first mesh network data packet has not been previously received by the wireless communication device and if the first lifetime value of the first mesh network data packet is not equal to a predetermined threshold value:
form a second mesh network data packet that is unaltered from the first mesh network data packet except that the first lifetime value is changed to indicate that the first mesh network data packet has been received; andtransmit the second mesh network data packet within a second data packet that is identified as being of the broadcast packet type.
