Description

technical field

[0001] The invention relates to the field of wireless sensor networks, in particular to a data link layer protocol performance testing method and system adopting the componentization idea. Background technique

[0002] The wireless sensor network is composed of a large number of cheap micro sensor nodes deployed in the monitoring area. It is a multi-hop self-organizing network system formed by wireless communication. Its purpose is to cooperatively perceive, collect and process the perceived Object information, and sent to observers. Compared with traditional networks, the complexity and changeability of wireless sensor networks determines the difficulties in its development and maintenance: macro system tasks must be completed through the division and cooperation of a large number of micro nodes, the interception of micro node data and the macro network status monitoring is very difficult.
