Simple data, such as temperature, humidity and luminary, gathered by nodes in wireless sensor networks (WSNs), can hardly meet the growing needs for real-time information. The availability of low-cost hardware is enabling the development of wireless multimedia sensor networks (WMSNs), i.e., networks of resource-constrained wireless devices that can retrieve multimedia content such as video and audio streams, still images, and scalar sensor data from the environment. However, multi-function means complex design, effective hardware, robust protocol and many other considerations. Comparing some of those current mainstream WMSN test beds, limits and shortcomings can be easily found. In this paper, MR. Eye is designed. Nodes, within MR. Eye, built on OMAP3530, are capable of coping with video, images and other real-time information. Moreover, the load balanced airtime with energy awareness (LBA-EA) is applied in this system and nodes can be easily controlled by SNMP gateway. The last but not the least, real-time video data can be transmitted fluently in multi-hop scenarios.
