Due to the mobile sensor is expensive and moving will consume a lot of energy. We used a small part of mobile sensor and most part of static sensors to meet the demand of k-coverage of three-dimensional network, and we have analysis the ratio of them is 1/(2πk^1/2. To achieve k-coverage, we have received the maximum moving distance for mobile sensor is O(log^1/3 in a network with a size of L . At last, we established a mathematical mobility model for mobile sensors, and converted the sensor redeployment for k-coverage into maximum network flow problem, and proposed a distributed relocation algorithm and verified it through experiment simulation.

To acquire the inherent topology properties and characteristics of the topology graph at AS-level, we introduce basic network model (Scale-free network and Small-world network) and evaluating parameters (such as cluster coefficient, average path length, degree distribution, Pearson correlation coefficient) in this thesis. Through thorough analysis of the topology of the generating topology at AS-level, we can see some apparent properties with the evaluating parameters and the inherent power-law distribution property of the derived topology. Besides, we discuss the perspective of the evolution of the networks topology based on these analyses.

The merits of Thomas Ford Brown's definition are:(1) Systemism implies a three-dimensional analysis that integrates well the individual egos in a network with the network structure, taking into considerations each proactive egos as well as the characteristics and influence of the whole network;(2) He emphasized that this is a processual system that indicates the interactive relations between components, structure and environment, giving the system a dynamic feature.

这一定义的优点是：（1）因为采取了三维的分析方法，他把网络中的自我和网络结构很好的包容在一起，这样既可以考虑到每一个自我的能动性，又能关注到整个网络的特点和影响；（2）他强调这是一个过程的系统，也就是指出要素、构成和环境三者之间的互动关系，使得整个理论呈动态特征。
