For real-time video transmission in multimedia sensor networks, efficient and reliable communication is very important. However, under actual conditions, when the sensor transmits data to the sink node, the link between the sensor and the sink node usually becomes unstable due to bandwidth limitations and unstable transmission links. Unstable data transmission will affect the normal data transmission of sensor nodes, and even cause sensor nodes to fail to communicate with sink nodes. These problems make users who use multimedia sensor networks have a poor user experience. In order to solve these problems, a brand-new multi-homed multi-connection system was designed for wireless multimedia sensors, and a prototype system was implemented. Compared with the traditional single-homed connection mode, the system can maintain a more stable connection under the same bandwidth, memory and CPU resource constraints.
