PROJECT TITLE :

Link Scheduling Method for Underwater Acoustic Sensor Networks Based on Correlation Matrix

ABSTRACT:

The unique characteristic of the underwater acoustic communication channel force development of latest protocols for underwater acoustic sensor networks. Especially, the gorgeous slower propagation speed of acoustic signals in underwater ought to be considered. This paper constructs a link scheduling model on medium access management (MAC) layer for multihop underwater acoustic sensor networks. The proposed model employs correlation matrix to describe the conflicts relationship among links and uses propagation delay to get conflict matrix for collision detection. In order to minimum the frame length, a power management strategy is introduced and aimed to scale back the result of link interference. Then, a heuristic algorithm is presented to resolve the conflict-free downside based mostly on the model. Simulation results show that the link scheduling methodology and the power control strategy can effectively improve network performance with respect to throughput and finish-to-finish delay.
