The wireless sensor network (WSN) is one new hot spot for both research and industry. However, the energy problem has been becoming a challenge in practical applications for WSN because the sensor nodes are supplied with energy by batteries which are difficult to be recharged and replaced. So many researches are taken on reducing the energy consumption of WSN nodes. Medium Access Control (MAC) layer...
The wireless sensor network is one new hot spot for both research and industry. Currently several communication protocols have been developed for wireless sensor network, including Zigbee, wirelessHART, ISA100.11a, WIA-PA, and so on. Most of these protocols are developed based on IEEE 802.15.4. IEEE 802.15.4 was designed for low-cost and low-power wireless network which provides MAC layer and physical...
Low-rate wireless personal network (LR-WPAN) is an emerging networking technique that was obtained more and more attention for its power efficient and low data rate applications. In this paper, we give a brief overview of WPAN and wireless senor network (WSN) protocols. Then, we focus on IEEE 802.15.4 which is the fundamental of many LR-WPAN protocols. Finally, we set up a simple experiment based...
