Embodiment Construction

[0046] a. The overall structure of the test system:

[0047] As shown in Figure 1, the hardware system includes a host computer, a PCI9840 interface card, several nodes with CAN controllers, CAN bus, and the PCI9840 interface card has 4 CAN interfaces, and 3 of them are used here. 10 nodes are connected to each interface to form a wireless sensor network test system with 30 nodes.

[0048] Among them, the PCI9840 interface card has strong data processing capability, greater instantaneous data throughput and safer hardware design. It uploads the communication data in the network to the host computer through the PCI bus, and is the interface between the CAN network and the host computer.

[0049] The software system includes host computer software and simulation node software templates. The host computer software works on the host computer and interacts with the network through the PCI9840 interface card to complete functions such as topology setting, node status monitoring, com...

Abstract

The test system thereof comprises: an upper-computer and several wireless sensor network simulation nodes. The nodes communicate with the upper-computer through a wired way. The method thereof comprises; 1) the test system downloads the simulation parameters from each simulation node; 2) the nodes make a variance process for its transmitted data message once transmitting data during working process; 3) during node networking, route selection, node on-line, node off-line, the test system records relevant working parameters without intermission; 4) comparing the recorded working parameters with the theoretical value of the algorithm in order to evaluate the senor network.
