空中传感器网络部署与优化问题研究

Aerial Wireless Sensor Network(AWSN) is a new kind of sensing network in the air, which is a combination of microminiature spacecraft and wireless sensor network with the capabilities of perception and communication.This project surrounds the core scientific issues of deployment and optimization in AWSN, mainly to carry out the following researches:(1)In order to improve the network segmentation and self-repair the holes in delopment, to set up a self-organizational network model with the characteristic of anti-collision, anti-dispersedness and high destroy- resistant, which is suitable for AWSN. (2) Based on the strong mobility of the nodes, a routing technology is investigated to adapt the dynamic topology of AWSN, a type of master-slave routing protocol which the nodes of it have the role mechanism is to be developed.(3)To study the three-dimensional deployment strategy under multi-restriction conditions and the optimization methods, especially how to overcome the contradiction of node mobility and spatial coverage in three dimensional space. The study on the problems of deployment and optimization in AWSN can not only promote the development of protocol and computing theory in wireless sensor network fields, but also provide important theoretical basis for the new applications of wireless sensor network.
