Research On Wireless Sensor Network Energy Consumption Balance For Airport Noise Monitoring

With the scale of airport transportation expanding, the level of airport noise pollution is worsening, therefore, installing airport noise monitoring system has been an important method for a lot of airport to monitor the surrounding noise environments. However, this kind of fixed monitoring point has high costs, high environmental requirements and poor stability. Noise in sensor node instead of fixed monitoring points to complete the data collection, transmission, treatment will become the future trend of development.Because the sensor node energy limited. Airport noise monitoring network must be effectively utilized in the sensor node energy to extend the network lifetime. Therefore, this minimal connected cover set problem in the study of the sensor node energy balance becomes particularly important.Firstly, target to minimal connected cover set problem of wireless sensor networks in airport noise monitoring, a centralized is proposed to construct a near optimal cover set of active sensors required to cover the target region completely. A connectivity based on minimum spanning tree algorithm is proposed to ensure coverage of CVT algorithm builds a set is required to connect the secondary node, and experimentally evaluate the performance of the algorithm.Secondly, target to noise monitoring network in the sensor node energy imbalance, proposed TERA energy balance routing algorithm based on network topology to reduce energy consumption in communication between nodes. Simulation results show that, using TERA algorithm gets longer network lifetime and noise monitoring node die very quickly in a very short period of time. Description energy balance model and algorithm for the design of a good balanced monitoring of energy consumption of the nodes, and the effect is to reduce communication energy consumption is ideal. In addition, noise monitoring at the airport how to divide a network into cluster is a direct cause of network energy consumption problem, made a broadcast-based coordinates SCTC static chain cluster routing algorithm for wireless sensor networks, used to eliminate network dynamic clusters of energy consumption.Finally, by joining the sensors node hibernate mechanisms to reduce network energy consumption, and with the same energy consumption model as well as its parameter compare no dormancy mechanisms in the context of the network, the simulation results showed that dormant nodes of networks is in working condition under the network has a longer network lifetime.
