Adaptive Transmission based Geographic and Opportunistic Routing in UWSNs

Abstract

UWSNs are frequency selective and energy-hungry due to the underwater acoustic communication links. We propose adaptive transmission based geographic and opportunistic routing (ATGOR) for efficient and reliable communication. Opportunistic routing is utilized along with geographic routing to select a set of forwarders from the neighboring nodes instead of a single forwarder. We propose a 3D network model logically divided into small cubes of equal volume with a goal that the sensed data is transmitted by the unit of small cubes.
