In this article we discuss the Quality of Service (QoS) requirements in WSNs and present a survey of some of the QoS multi-parameters metrics in WSNs. Also, it gives the performance of 802.15.4, LEACH, and CBRP protocol considering parameters. The simulation tests were carried out by the simulator NS 2.29;it showed that the performance of 802.15.4 protocol is better than the LEACH. The results have shown that the 802.15.4 standard protocol provides better quality of outperformed service requirements than LEACH protocol. So its performance in WSNs is more effective than LEACH protocol. CBRP protocol simulators NS 2.34, reduce traffics and congestion packet. Finally, the algorithm CBRP offers optimal performance with reduced overhead and delay with respect to the other two protocols. Plus, the strengths and weaknesses of the protocols are specified in relation to the provision of quality of service. It should take effective action to address them.展开更多
