%X The Internet of Things (IoT) is regarded as the future generation Internet, which ranges from radio frequency identification (RFID) to the ubiquitous computing systems such as wireless sensor networks and mobile ad hoc networks. With the rapid development of IoT, designing an effective low-cost embedded terminal device for the IoT become very necessary. A new embedded device, Webit&NEU, and its reduced embedded real-time operating system used for IoT are implemented by our China Liaoning Province Embedded Technique Key Laboratory in this paper. Besides, related modules in terms of RFID technique, wireless communication, and network protocol are also provided in this paper. Compared with several current solutions of connecting devices and Internet, it has the advantages of good real-time performance, light weight, and low cost. Besides, this paper also puts forward a localization algorithm for the Webit&NEU, and experimental test results in terms of real-time system ability, network communication performance, and localization algorithm show that Webit&NEU can work well and meet the actual requirements of the IoT. 1. Introduction The IoT is a new-emerging technique. After the age of Internet and wireless sensor network, people are gradually entering the era of IoT. The IoT refers to uniquely identifiable objects (things) and their virtual representations in an Internet-like structure [1]. In fact, the IoT includes technologies such as RFID, sensors, and smart devices. The concept of the IoT has become more and more popular now. RFID is often regarded as a prerequisite for the IoT [2, 3]. Supposing all objects of daily life were equipped with radio tags, thus they could be identified, tacked, and managed by computers, and then they will certainly bring great convenience to people¡¯s lives. Embedded Internet device Webit2.0 can make the standard industry device have the ability of accessing the Internet, and it has successfully been embedded to fieldbus, industrial devices, and so forth, so people can feel free to access those devices through Internet. Webit2.0 has been successfully developed by our China Liaoning Province Embedded Technique Key Laboratory and has been large-scaly manufactured by China Shenyang Neu-era Information Technology Stock Co., Ltd [4]. It is worth noting that Webit2.0 has obtained the China's product patent (nos. ZL 00 2 52482.1 and ZL 01 2 29725.9). The design and implementation of embedded device Webit&NEU are based on Webit2.0. Besides the basic functions of Webit2.0, new functions such as RFID data processing and wireless date
