Efficient Packet Delivery for Underwater Acoustic Sensor Networks

摘要

Underwater acoustic sensor networks (UWASN) is an important tool of human to monitor the ocean. However, the existing routing has problem of low packet delivery, the long time end to end delay and the redundant packets. A new routing IGDAR is proposed in this article. The IGDAR select candidate node that the distance to the sink is minimum, and compose a candidate forwarder set. Theoretical analysis verifies the effective of IGDAR. Simulation results show that IGDAR increase the packet delivery by 54.3%, reduce the end to end delay and redundant packet by 2.5% and 12.5%, respectively.
