The Energy Consumption Analysis of Optimal Coverage for Freeway Information Monitoring in Wireless Sensor Networks

Abstract:

Applications of wireless sensor networks (WSN) in freeway information monitoring are rapidly expanded. The freeway optimal sensing coverage and efficient energy consumption problems are the fundamental requirement for the freeway information monitoring systems based on WSN. This paper firstly surveys the coverage model which is considering the sensing range of sensors and the width of the freeway. And then analyzes the system energy consumption performance based on this coverage model. The result shows that the network lifespan is very bad because the imbalance energy consumption. Therefore, several improved strategies are discussed in detail, which are to balance the energy consumption and prolong the network life span through increasing appropriate sensor nodes on the both sides of freeway and scheduling these redundant nodes to sleep mode.
