Design of a Self-Organizing Routing Protocol for Underwater Wireless Sensor Networks Based on Location and Energy Information

Underwater wireless sensor networks (UWSNs) are significantly different from terrestrial in the following aspects: low bandwidth, high latency, variable topology, limited battery, processing power and so on. These new features pose many challenges to design of self-organizing routing protocol for UWSNs. This paper focuses on application Ad Hoc On-demand Distance Vector (AODV) In order solve problems packet collision excessive energy consumption associated with flooding-based discovery method periodic hello maintenance mechanism AODV, a based location information is proposed, it referred as route-focusing AODV (RFAODV) protocol. RFAODV protocol, process focused few nodes through forwarding area control dynamic delay adjustment. addition, feedback media access layer residual used maintenance. We implement evaluate its performance according sea trial data parameters NS-2. The simulation results show that compared other protocols, improves success ratio by at least 18%, increases transmission 4%, reduces overhead 15% 5% under various scenarios. suitable large-scale, high-load underwater networks.
