CLUSMOB Protocol based on Clusters for Mobile Underwater Networks

Abstract

The need for underwater wireless sensor networks having mobile sensor nodes has been there for a long time in form of underwater warfare or explorations by Autonomous Unmanned Vehicles (AUVs) or Remote Unmanned Vehicles (ROVs). The constant and random movement of the sensor nodes makes it difficult to select the next forwarding node because it is quite obvious that nodes can go away from the gateway node due to movement. This results in increased end-to-end delay and inefficient energy consumption by the sensor nodes. There are very few protocols for ad hoc mobile underwater wireless sensor networks (AMUWSN). Thus, we present an ad hoc Mobile routing protocol for AMUWSN. Designing a protocol for AMUWSN is quite challenging for the reason of its continuous random movement of the sensor nodes. These sensor nodes may need to communicate with each other and with the gateway (GW). The proposed protocol is a self-organizing routing technique based on clusters that use received signal strength (RSS) for distance estimation.
