In the communications protocol standard IEEE 802.15.4 MAC has established a network device properties are two types: (1) A device that has a full (Full Function Device, FFD) and a device that has some. The (Reduced Function Device, RFD) (2) the performance of the FFD and RFD different FFD can be contacted with any node while RFD can not communicate with other nodes and is limited to. only to FFD RFD nodes communicate, but it was limited in terms of energy and inexpensive to use. Thus cutting out unnecessary functions as a mechanism to route (Route) on the establishment of a network of wireless sensor device FFD and RFD of PANs (Personal Area Networks).
