PERFORMANCE MONITOR, EVALUATION AND DIAGNOSIS SYSTEM FOR WIRELESS SENSOR NETWORKS

摘要

A method of evaluating and diagnosing performance of an operating wireless sensor network without disturbing or burdening the network is disclosed. The operating wireless sensor network includes a plurality of operational nodes. A system, which comprises a plurality of detecting nodes and a performance evaluation and diagnosis platform, is provided in order to implement the present method. After time synchronization, the detecting node is connected with an operational node. After the detecting node estimates MAC or network layer address of its corresponding operational node, it will capture any transmission of or around the operational node, and upload captured packets to the evaluation and diagnosis platform. The evaluation and diagnosis platform produce a report by analyzing the acquired information from all detecting nodes.

1. A wireless sensor network (WSN) monitor system, comprising: one or more detecting nodes, each detecting node including (i) means for time synchronizing with other detecting nodes in the WSN monitor system; (ii) means for acquiring an identification of at least one operational node of the WSN; (iii) means for capturing signals transmitted to and from the identified operational nodes of the WSN; and (iv) means for adding an identifier to the captured signals to form a recorded message.
