TCP/IP to the wireless sensor node.

During a presentation about wireless sensor networks to the WSN-SIG in 2005, David Culler of Arch Rock said, “Don’t bet against IP.” Recents events seems to confirm that prognostication for wireless sensor networks. Zensys, who makes chips for “other Z protocol” Z-wave, publicly announced their intention to integrate TCP/IP with their proprietary low power wireless protocol. Their “Z/IP” protocol will be licensed. In other news, the IETF effort, 6lowpan, to merge IPv6 and low power wireless sensor networks has received attention in that a company is already open-sourcing their 6lowpan implementation. (This comes on the heels of the “free MAC campaign” where 802.15.4 implementations are being open-sourced or given away.
