A Survey on ZigBee/IEEE 802.15.4 Technology in Wireless Sensor networks
PhD Qualifying Examination Title: "A Survey on ZigBee/IEEE 802.15.4 Technology in Wireless Sensor networks" by Mr. Tong ZHU Abstract: Wireless sensor networks have been rapidly developed within recent technologies advanced. Sensor devices consist of sensing components, data processing components and communication components to deal with data automatically collected from various environments. However, constrained by the low-cost and low-power devices, the sensor nodes do not have powerful communication abilities. Therefore, industry and research community proposed ZigBee/IEEE 802.15.4 standards which focus on the very low-cost communication of nearby devices. In particular, the IEEE 802.15.4 standard is designed for the physical and MAC layers and the ZigBee standard for the network and application layers. In this survey, We will give the overview of the 802.15.4 and ZigBee standards, especially emphasis on the problems and challenges we faced in the real applications, and compare the solutions and ideas proposed in the recent literatures. The problem mainly focus on improving the throughput performance in WSNs. The solutions will be divided into three categories: Transport layer solutions, MAC layer solutions, Cross layer solutions. The advantages and disadvantages of each solution, as well as the various principles, will be emphasized for comparison. Finally, we will try to discuss some problems that exist alongside which we could carry on in other future research directions.
