摘要：ZigBee wireless sensor and control network is one of the most popularly deployed wireless technologies in recent years. This is because ZigBee is an open standard lightweight, low-cost, low-speed, low-power protocol that allows true operability between systems. It is built on existing IEEE 802.15.4 protocol and therefore combines the IEEE 802.15.4 features and newly added features to meet required functionalities allowing it in finding applications in wide variety of wireless personal area networked systems such as home/industrial automation and monitoring systems. The previous researches on the ZigBee have been focused on its network performance characteristics such as energy efficiency, throughput, packet delay and delivery ratio in different scenarios and applications. This research paper evaluates the ZigBee data accuracy, network implementation and security challenges in ZigBee star and mesh topologies with concentration on its home monitoring application.
