ABSTRACT
In the last decade, plenty of research has been conducted in the ¦eld of wireless sensor networks (WSN). One important part of a WSN node is its communication interface. Starting with proprietary communication systems in early days of WSN, standardized communication interfaces are required today. IEEE 802.15 wireless personal area network (WPAN) task Group 4 has de¦ned a low data rate communication protocol with low energy consumption. IEEE 802.15.4 de¦nes physical (PHY) and medium access control (MAC) layers and is widely used in current WSN. ¥is standard forms a basis for other emerging upper layer standard protocols, like ZigBee, WirelessHART, and SP100. While those protocols are established in home automation, building automation, and factory automation, Internet protocol (IP) connectivity is still desired.
