Main Article Content

Hemanth Kuppili


This paper compares the physical charateristics of different communication channels required for efficient exchange of information via underwater wireless sensor networks. These include physical waves like sound, radio, and light waves as the possible carriers among the nodes in an underwater sensor network. A comparision of the pros and cons for adopting different communication carriers (acoustic, radio, and optical), based on their physical characteristics and reliable utilisation is made. The review mainly focuses on densely deployed nodes placed in underwater sensor networks. Based on the comparison study, the most efficient communication carrier for underwater sensor networks is recommended.
