Abstract: This paper analyses the schedule mechanism of TinyOS, which is a representative operating system of WSN, and also points out some shortages of TinyOS. Then some improving methods are presented accompanied with the realization of prioritized task schedule scheme. The simulation result and application result on the actual WSN system-GAINS indicate that the priority schedule of TinyOS can improve communication performance significantly.

Key words: Wireless sensor networks, TinyOS, Schedule strategy, Priority
