Establishment of Data Collection and Transmission Optimization Model Based on TRIZ

摘要

This paper is aimed at solving the problem in the data acquisition process of WSN network, such as energy problem, the correlated problem of data acquisition and the dynamic problem of network topology. An efficient data collection solution based on TRIZ contradiction matrix and innovation principle is presented in the paper. Firstly, the contradiction matrix is used to obtain the corresponding principle, and then the appropriate and feasible principles are selected and applied, taking into account a variety of main factors. Secondly, considering the energy and correlation of nodes as well as the capacity, we get a feedback and correct the node weight according to the principle of separation and feedback based on LEACH algorithm. Finally, we establish the optimized model to collect data efficiently. The simulation and experiments prove that the optimized model can effectively reduce the consumption of the energy and prolong the lifetime of the network.
