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。

The method comprises the following steps:(1) the nodes of the sensor adopt the delaminated structure; the program memorizer is divided into the microkernel region and the user program region; the microkernel region is a fixed region; and the user program region is a nonupdatable region;(2) in the sensor network, a function upgrading code image is encapsulated into a data packet and injected to the network by a sink node; under the control of the microkernel region, the data packet is diffused in the whole network in a gradual jumping mode and sent to each node of the network; and (3) the nodes of the sensor utilize the delaminated structure to realize the self-function updating, thereby completing the self-maintenance of the function of the nodes.

其步骤如下(1)传感器节点采用分层结构，程序存储器分为微内核区和用户程序区，微内核区为固定区，用户程序区为不可更新区。(2)传感器网络中sink节点将功能更新代码映像装入数据包并注入网络，在微内核区的控制下，数据包以逐跳的方式在整个网络中扩散，传送至网络中的每个节点。(3)传感器节点利用分层结构来实现自身的功能更新，完成节点的功能自维护。
