Analysis of IEEE802.15.4 network performance comprehensive evaluation and prediction

The performance comprehensive evaluation and prediction of IEEE802.15.4 network is important for network planning and management. The model of comprehensive evaluation of network performance and the prediction, are built based on the multiples index. In the test of simulation, the actual applications were simulated by changing the node scale. In the test, network latence, packet loss and throughput were selected as a performance metric to access the data of the network performance. It´s easy to known from the analysis of the model that the model of comprehensive evaluation of network performance and the prediction could avoid the influence caused by human factors, and it can objectively and accurately evaluate the comprehensive performance of the network. At the same time, the method also has the features of good flexibility and strong adaptability.
