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.

考虑移动传感器移动会大量消耗能量，且比较昂贵，使用小部分的移动传感器和大部分静止传感器来满足网络k-覆盖的密度需求，且分析了其密度之比为1/(2πk^1/2；并证明了网络要达到k-覆盖传感器需移动的最大距离为O(log^1/3；建立传感器移动数学模型，将传感器重新部署问题转化为最大网络流问题，提出分布式重新部署算法并实验仿真证明其有效性。

The goal of a CSCW system is to enable users to cooperate conveniently no mater when and where While,currently,most CSCW users rely on existing network infrastructures Self organized Network is a multi hop temporary autonomous system of mobile nodes equipped with wireless transmitters and receivers without the aid of any current network infrastructure In such an environment,it may be necessary for one mobile node,in order to communicate another node,to need a chain of intermediate nodes to forward pac...

CSCW 系统目标是允许用户在任何地点，在任何时间可以方便地进行群体间的协同工作。目前大多数的CSCW 用户都需要依靠现有的网络基础设施。自组网是一组带有无线收发装置的移动节点组成的一个多跳的临时性的自治系统。在这种环境中，由于节点无线通信覆盖范围的有限性，需要借助其他中间节点进行分组转发到达信宿。它可以在没有可用的网络基础设施的情况下提供一种通信支撑环境，从而拓宽了CSCW 的应用环境。本文描述了自组网的概念和特点，并提出了自组网的体系结构。

In the network JY played a year, I to have always been and then have no to feel the interpersonal exchanges, because I am not a Chinese, I is 1 the year ago go to when traveling China buy to the game card of 1 network JY, return to Seoul's home the empress, and I packed to ascend the gamed, but computer and the manifestation of the nonsupport Chinese language, therefore I please friend who study abroad in China purchased a Taichung country computer, computer 托 that produce the 运 go to Seoul is already octobered, and pack the game to behind see to see to new- break throughed Fuzhou to stand, I and incognizant Chinese characters, literally choose and then enter, pass by donkey years of grope for, and I understand the game, and feel the Chinese to think the elephant dint very abundant, the Mr. JY novel also write of very stick, I do not understand the Chinese language, therefore I play the network JY resemble at play the single game, many people to request to chat with me, I see to not understand, therefore can't with everybody exchanges.

在网络JY中玩了1年，我从来就没有感觉到过人与人之间的交流，因为我并不是中国人，我是1年前去中国旅游时买到了1张网络JY的游戏卡片，回到汉城的家里后，我装上了游戏，但是电脑并不支持汉语的显示，所以我拜托在中国留学的朋友购买了一台中国生产的电脑，电脑托运到汉城时已经是10月了，装了游戏后看到看到新开通的福州站，但是我并不认识汉字，随便选了就进入，经过很久的摸索，我了解了游戏，觉得中国人的想象力很丰富，JY先生的小说也写的很棒，但是因为我不懂汉语，所以我玩网络JY就像在玩单人游戏，很多人要求和我聊天，但是我看不懂，所以就无法和大家交流。

After discussing the structural conditions of the existence of the active network solutions, the state equations in normal form over F of electrical network which are suited for studying the character of network structure are derived.
