Performance Comparison of Sensor on/off Based on Polling in Algorithm Wireless Sensor Networks

Abstract

Today, wireless sensor networks are widely used in the field of intelligent transportation system. For areas with different vehicle densities, the amount of data that needs to be wirelessly transmitted to the central server is different. In this paper, we propose a new data transmission scheme, i.e., the Sensor On/off scheme based on Polling Algorithm (SOP). In specific, we are going to realize one no packet loss scheduling transmission mechanism in different service density areas, and have effectively integrated switching technology into SOP. That is, when the sensor is idle, we can turn it off to achieve the goal of reducing energy consumption. Finally, we compare the SOP with the random scheme and sequential scheme. It is proved by the analysis results that SOP can effectively reduce the energy consumption of data transmission in wireless sensor networks.
