The mobile sensor node comprises a master control subsystem, a sensor subsystem, an execution subsystem and a communication subsystem, wherein the master control subsystem comprises a microprocessor, a storage, an I / O drive circuit, a power supply circuit and the like; the sensor subsystem plays a role of acquiring and processing environment data and transmitting the processed data to the master control subsystem; the execution subsystem completes the action under the driving of a mechanical drive structure through a direct current motor; and the communication subsystem realizes wireless communication among the mobile sensor node, the static sensor node and the sink node.

Description

technical field [0001] The invention relates to a scientific experiment platform, in particular to a device for experimental research on mobile wireless sensor networks. Background technique [0002] Traditional wireless sensor network research experiments are based on static nodes. However, static wireless sensor networks (all nodes are stationary) inevitably have problems such as energy holes, redundant coverage, and hot spots. Many existing wireless sensor network applications have introduced mobile sensor nodes to solve the above problems. [0003] Some existing mobile sensor nodes have some defects, such as expensive, slow moving speed, small amount of data storage, and not abundant external expansion interfaces. Some mobile sensors are formed by purchasing a robot car and connecting an external sensor, so that communication and movement cannot be organically combined and cannot meet the requirements of scientific experiments. Contents of the invention [0004] Tec...
