The Elementary Study Of Communication Protocol On Sensor Network

The old monitoring systems often put a few high-power sensors with strong ability of data-analyzing near the observation site which was near to the target. This system has many defects. The data was not nice. The sensor must have strong ability of data-processing. It must take some useful signals out of the intermix signals. Now we can produce the sensor which was small, consuming a little energy, costing small and function high. We can obtain fully and nicely data by putting sensors near the observation district with high density.Sensor network, which is made by the convergence of sensor, nested computation, networks and wireless communication technologies, is a novel technology about acquiring and processing information. It is a wireless network of infrastructure network and can be used for testing, sensing, collecting and processing information and send the information to the user who needs it. So it has a wide application future.The article firstly narrates the researching background, the present researching status throughout the world, the need and meaning of the researching, the main content and the source of this subject. The main content of this article is as follows: it firstly introduce the data-diffusing arithmetic to the sensor networks; secondly the design of the sensor network protocol; thirdly the design of the communication protocol of tracking mobile target; because the number of the sensor networks are numerous and single node is limited in resource. The chiefly aim of designing routing protocol of sensor network is to reduce the overall energy consumed in the network and to maximize the network lifetime. The article analyzed and compared some routing protocols that proposed by oversea researcher and pointed out each bug. Consequently we introduced the data-diffusing arithmetic to the sensor networks. Finally we designed a communication protocol for tracking the mobile target. The protocol that we designed is based on the negotiation mechanism. In the view of network structure, it partitioned the sensor network into...
