Abstract
The invention relates to the field of IEEE 802.15.4 based networks, and in particular to methods and devices for transmitting and receiving messages in IEEE 802.15.4 based networks. The existing IEEE 802.15.4 standard is further improved and adapted to better fit the properties of a network of lighting devices. The improvements and adaptations of the existing IEEE 802.15.4 standard allow for more flexible addressing. Bits which are indicative of use of address fields and/or whether one or two frame control fields is/are present in the ordered data portions of the message to be transmitted are defined by the device transmitting the message in the IEEE 802.15.4 based network. Existing features of the existing IEEE 802.15.4 standard protocol are retained.
