A brief study on low-rate wireless personal network

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 on NS2 platform to evaluate the performance of it.
