An adaptive sequential diagnosis algorithm is presented based on the point to point network by abstracts the three test models common characters,and its test model,diagnosis strategy,diagnosis costs are estimated.

The Localization Technology Based on TDOA for Wireless Sensor Network Nodes;

According the speciality of wireless sensor network technology and alarming in intelligent home,we designed an alarming system based on wireless sensor network technology,built the structure picture of alarming system,and designed the network node and software of the alarming system.

Such design enhances the flexibility of the system and improves the reliability of the network nodes.

The difference between the process pinch and network pinch has been analyzed.

A Network Node Architecture Based on Active Technology;

One of the main causes is lacking node resources and poor management, such as the buffer in network node.
