How large/small a ZigBee Network can be?
top The addressing space allows of extreme node densityup to 18,450,000,000,000,000,000 (264) devices (64 bit IEEE address), which may form different topologies depending on customer needs: star, mesh, cluster tree. At the same time, using local addressing, simple networks of more than 65,000 (2^16) nodes can be configured, with reduced address overhead. How is the Data Security provided? top Its important to provide your sensor network with adequate security to prevent the data from being compromised, stolen, or tampered with. IEEE 802.15.4 provides authentication, encryption, and integrity services for wireless systems that allow systems developers to apply security levels as required. These include no security, access control lists, and 32-bit to 128-bit AES encryption with authentication. This security suite lets the developer pick and choose the security necessary for the application, providing a manageable tradeoff against data volume, battery life, and system processing power re
