VAPR: Void Aware Pressure Routing Protocol
UnderWater Acoustic Sensor Networks (UW-ASNs) have lately been suggested as a potent means of supporting aquatic applications ranging from environmental monitoring to intrusion detection. A bevy of mobile sensor nodes each equipped with a variety of sensors and a low bandwidth acoustic modem (e.g. Drogues) can be deployed the region of interest to form an ad-hoc network. The sensor network forms what is known as a SEA Swarm (Sensor Equipped Aquatic Swarm), where each individual node is capable of moving with the underwater jet streams and currents. The swarm is escorted by sonobuoys at the sea surface which are equipped with both acoustic and radio modems (Wi-Fi or satellite) and GPS.
