Abstract: The energy consumption of nodes in the wireless sensor networks directly affects the enduranceof the nodes. Optimization of the MAC protocol can effectively solve the energy consumption problem ofnodes. A prioritized wireless sensor network MAC protocol is studied based on TinyOS, a wireless sensornetwork operating system. The actual hardware node CC2538 is used to explore the improvement of theMAC protocol and the verification of its performance. The results show that the proposed prioritized MACprotocol for wireless sensor networks has better OoS guarantee when the load is high, and can effectivelreduce the energy cost of nodes.

Key words: quality of service;wireless sensor network, MAC protocol
