- Title
A MAC Protocol for Clustered Underwater Acoustic Sensor Networks.

- Abstract
This paper proposes a MAC protocol based on time-division multiple-access (TDMA) for clustered underwater acoustic sensor networks (UW-ASN), which is named Cluster-TDM A (C-TDMA). C-TDMA mainly consists of scheduling stage and transmission stage. In scheduling stage, the transmissions of sensor nodes causing inter-cluster interference are scheduled first by the gateway node. Then cluster head nodes separately schedule the transmissions of other nodes in their own clusters. In transmission stage, sensor nodes periodically send data packets which finally converge to the gateway node to cluster head nodes according to schedule table. C-TDMA simply and effectively solves the problem of scheduling the transmissions of sensor nodes causing inter-cluster interference. The C++ simulation results show that C- TDMA works well in terms of throughput and energy efficiency.
