Improvement And Simulation Of LEACH Algorithm For Wireless Sensor Network

Wireless sensor network (WSN) is one of the most cutting-edge and the mosthot research problem in the world today, which has begun a variety of applications inall aspects, and even many related products have come into our daily lives, bringing avariety of convenience to our lives. At the same time, with the rise of the Internet ofthings, the study of wireless sensor network is once again pushed to the cusp in recentyears, and combining the Internet of things with wireless sensor network has becomea research hot spot, predictably, the new network technology in combination withwireless sensor network technology will bring great changes to our daily life in thenear future.Routing algorithm of wireless sensor network is the one of the mostimportant key sensor network technologies in the entire sensor network technology,the quality of a sensor network routing algorithm used is directly related to thereliability of data transmission across the network and the life cycle of the entirenetwork. When people are just beginning to study wireless sensor network routingalgorithm, the traditional internet routing technology is in first considered to usedirectly. After an in-depth analysis and research, it is found that there are manydifferences between them. Therefore, through the analysis of the existing wirelesssensor routing protocol, it plays a very important significance for the actualproduction and life to improve and design new routing algorithm of wireless sensornetworkIn this paper, we will do in-depth research and analysis of LEACH routingalgorithm which is one of the most popular routing algorithm in wireless sensornetworks now. Through the analysis of the related problems of LEACH routingalgorithm improvement plan is put forward and finally on the basis of all theimprovement programs, it is designed for a complete improvement LEACH algorithmwhich simulated with the simulation tool. In the algorithm of the improvement, wegot the information of sensor nodes through using GPS positioning to establishvarious clusters and corresponding routing table information. Just the establishment ofthe routing table is completed, and then the data in the process of transmission cansave a lot of time to look for and establish the transmission path. For cluster headnodes, the improvement algorithm is used to average energy consumption rate ofcluster head nodes and common sensor node and prolong the life cycle of the wholenetwork as much as possible. In the final chapter of the paper, simulation softwarebased on the OMNET++is used to simulate the LEACH algorithm and the improvement algorithm, and the corresponding results is compared, we can know thatLEACH improvement algorithm is earlier than LEACH algorithm on the appearanceof time of death node, but the LEACH improvement algorithm significantly moreslower than the original algorithm on the time of node decline, therefore theimprovement LEACH algorithm does prolong life cycle of the network from the pointof view the entire life cycle of wireless sensor network.
