Experimental Design and Analysis of LEACH Protocol and Improved Algorithm
Many sensor nodes need to be randomly distributed in the area to be detected to collect information during application of wireless sensor network. Effective transmission of the information to observers is a key problem to be solved by routing protocols and an important factor determining the performance of wireless sensor network. From different points of view, different types of routing protocols are present. In order to help students understand and design routing protocols, the experiment is presented during teaching in this study. First, the principles of the LEACH protocol and the improved algorithm were analyzed. Second, the program of the LEACH protocol was implemented under the environment of MATLAB R2014a, which was run to analyze the operation of LEACH protocol, and the relationship between live nodes in network and run round number was summarized. Finally, LEACH protocol and improved algorithm were compared by experimental design and analysis. By relevant experiments, students can understand and apply the principle of LEACH protocol and relevant routing technology, and further understand the role of routing protocol, resulting in enhanced interest in learning.
