The Environmental Information Monitoring Network Set up based on Service Discovery Mechanism

摘要

The wireless sensor network is widely used in the largely data measure. The research on the energy consumption is the key point in it's practical application recently for the wireless sensor network has the problem of energy restrain. Considering the wireless sensor network applies in the information monitoring system on environmental has the inadequate of the limited energy of nodes and the irregular network energy consumption, this paper analyses the basic structure of the environmental sensor network, and proposes the service discovery mechanism based on the catalogue model. This system can reduces the system's energy consumption, and is able to achieve the purpose of increasing the reliability and security of the sensor network, reducing the data redundancy degree and extending the lifetime of the network according to the experimental simulation.
