Energy Efficient and Secure Routing for WMSNs Using Directional Antenna

Mika Matsushima and Ryo Katsuma

ABSTRACT 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. We formulate a routing problem to dynamically create streaming-data transfer paths for WMSNs constructed by sensor nodes with directional antennas, and we propose a method to solve this problem by scheduling the condition (sleeping or active) and the antenna direction for each sensor node. When the video data stream is requested by multiple users, the proposed algorithm reduces the total energy consumption among relay nodes by merging transfer paths. Simulation results confirm that the proposed method can conserve the battery power of each node for a WSN with 198 nodes. Keywords:- wireless multimedia sensor networks, directional antenna, routing, paths for streaming data
