Wireless Multimedia Sensor Networks (WMSNs) can deliver multimedia data such as streaming video to multiple users by sensor nodes deployed in a field. The major problems of Wireless Sensor Networks (WSNs) are radio eavesdropping and radio interference. Several studies have attempted to address these problems by limiting the reachable radio wave distance of each sensor node using directional antennas. The authors formulate a routing problem to dynamically create streaming-data transfer paths for WMSNs constructed by sensor nodes with directional antennas, and they propose a method to solve this problem by scheduling the condition (sleeping or active) and the antenna direction for each sensor node.
