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.
