Provides a comprehensive, in-depth look at the issues surrounding IEEE 802.15.4 network operation and performance. This book provides an in-depth analysis of the recent IEEE 802.15.4 standard for low data rate wireless personal area networks (LR-WPANs), including suggestions to improve performance and comparisons with the related 802.15.1 (Bluetooth) standard. It also assesses the suitability of the standard for the development and deployment of wireless sensor networks as well as providing guidance and insight into the relative advantages and disadvantages of various performance solutions. Includes a mathematical analysis of the results of published research from the last three years using the framework of Markov chain modeling for students studying courses in performance evaluation and wireless communication networks Compares several ways in which interconnecting single cluster networks to form multi-cluster networks can be implemented and multi-cluster lifetime extended. Discusses security issues in WPANs with in-depth analysis of different security threats, their impact on performance, standard security mechanisms, and security policies Compares the IEEE 802.15.4 standard with the related Bluetooth 802.15.1 standard in terms of suitability for implementing wireless sensor networks. A "must read" for developers and researchers getting acquainted with various aspects of 802.15.4 technology and graduate students studying courses such as Performance Evaluation, Wireless Sensor Networks and Queuing Theory.
