A Mac Protocol for Tactical Underwater Surveillance Networks

We introduce power controlled and loosely synchronized (PCLS) MAC protocol for Tactical Underwater Surveillance System (TUSS). PCLS protocol employs loosely synchronized listen-sleep schedules, and transmission power control. Shorter preamble signals are used instead of RTS/CTS handshake. These reduce the energy consumption and the link layer delay, and also make PCLS resilient against topology changes due to node failures and mobility. PCLS protocol is evaluated through the simulation of TUSS scenario where the mobile objects drift over the sea surface with respect to the reference point group mobility (RPGM) model. It is also compared with IEEE 802.11, B-MAC and LMAC.
