Coexistence of wireless sensor networks with other wireless networks |
| 摘要 |
A wireless device includes a wireless transceiver configured to transmit to and receive from nodes in a wireless sensor network (WSN) and control logic coupled to the first wireless transceiver. The wireless transceiver transmits a wireless packet to a node in the WSN based on the transmission coinciding with a break in transmissions for a second wireless network. Based on the wireless transceiver being configured to transmit the wireless packets utilizing time synchronized channel hopping, slot frames for packet transmissions in the WSN are time offset so as not to coincide with transmissions made on the second wireless network. Based on the wireless transceiver being configured to transmit the packets utilizing coordinated sampled listening, wake up sequence transmissions for the WSN are time offset so as not to coincide with the transmissions made on the second wireless network. |

1. A wireless device, comprising:
a first wireless transceiver configured to transmit to and receive from nodes in a wireless sensor network; and control logic coupled to the first wireless transceiver, wherein the control logic causes the first wireless transceiver to transmit a wireless packet to a node in the wireless sensor network based on the transmission coinciding with a break in transmissions for a second wireless network; wherein, based on the first wireless transceiver being configured to transmit the wireless packets utilizing time synchronized channel hopping (TSCH), the control logic is configured to cause TSCH slot frames for wireless packet transmissions in the wireless sensor network to be time offset so as not to coincide with transmissions made on the second wireless network; and wherein, based on the first wireless transceiver being configured to transmit the wireless packets utilizing coordinated sampled listening (CSL), the control logic is further configured to cause wake up sequence transmissions for the wireless sensor network to be time offset so as not to coincide with the transmissions made on the second wireless network. |
