Abstract
Various methods of operating a wireless mesh network are disclosed herein. According to various embodiments, an Internet Protocol (IP) router generates IP addresses for wireless sensor nodes that do not have native support for the IP protocol stack. The IP router then receives and translates an incoming IP request and routes the incoming IP request to the appropriate wireless sensor node. In some embodiments, an IP data packet can be encapsulated and routed using an IP router and an IP bridge device. In other embodiments, an Internet Control Message Protocol (ICMP) session can be managed over a wireless mesh network.
Claims20
A method for transferring an Internet Protocol (IP) data packet from an originating device to a receiving device, the method comprising:
- receiving the IP data packet from the originating device at an IP router;
- using the IP router to encapsulate the IP data packet into a wireless data gram;
- forwarding the wireless data gram to an IP bridge device;
- using the IP bridge device to unencapsulate the wireless data gram to the IP data packet;
- and
- using the IP bridge device to forward the unencapsulated IP data packet to the receiving device.
A system for transferring an Internet Protocol (IP) data packet from an originating device to a receiving device, the system comprising:
- an IP router that receives the IP data packet from the originating device, encapsulates the IP data packet into a wireless data gram, and forwards the wireless data gram to an IP bridge device;
- and
- the IP bridge device, which unencapsulates the wireless data gram to the IP data packet and forwards the unencapsulated IP data packet to the receiving device.
A method for transferring an Internet Protocol (IP) data packet from an originating device, the method comprising:
- receiving the IP data packet from the originating device at an IP router;
- using the IP router to encapsulate the IP data packet into a wireless data gram;
- forwarding the wireless data gram to another device;
- using the other device to unencapsulate the wireless data gram to the IP data packet;
- using the other device to encapsulate an IP response packet;
- and
- forwarding the encapsulated IP response packet to the IP router.
