OSI Layer 1 and 2 are IEEE 802.15.4 but Layer 3 can be ZigBee XOR 6LoWPAN. To avoid some license issue you can write a implementation in userspace which uses 802.15.4 adress family sockets. I mean with zigbee is a trademark we don't have rights to name this project "*zigbee*". 6LoWPAN is an alternative for zigbee and have nothing to do with zigbee. There are mainly two rfc [1] [2] and a lot of work to implement it. :-) 6LoWPAN is a compressed format for a simple ipv6 packet, look [1] for the header compression. ZigBee is more commercial and have device classes(which 6LoWPAN doesn't have). But top on 6LoWPAN and udp/(tcp) you can put whatever you want. - Alex [1] http://tools.ietf.org/html/rfc6282 [2] http://tools.ietf.org/html/rfc4944 ------------------------------------------------------------------------------ LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
