Survey on Geographic Routing Protocols in Underwater Wireless Sensor Network

Unlike Terrestrial Wireless Sensor Network(TWSN), Underwater wireless sensor network(UWSN) have different characteristics such as narrow bandwidth, long propagation delay and high packet loss. Hence, routing protocols used for terrestrial sensor network are not applicable in underwater network. This paper presents a detailed survey of geographic routing protocols used in underwater wireless sensor network and are compared based on their requirements and performance. nbs
