Link Quality Estimation VBF Routing for Underwater Wireless Sensor Networks (UWSNs)

The Underwater Wireless Sensor Networks are necessary for many applications such as marine search and underwater monitoring like measuring water speeds, currents and temperatures. The challenges is, needing for the special underwater environment, which is, require specified routing and security protocols and the traditional protocols are suffer many problems. Therefor there is continuous motivation for search and develop to enhance its performance in viral applications. Vector Based Forwarding is an Underwater Wireless Sensor Networks protocol. This protocol recognized by its depending on defaults pipelines for routing, the packets are routed through these pipes. The disadvantages of this protocol are, the sensitivity to the pipes radius, which is effect on routing efficiency and in the case of spaces found (voids) the protocol may fail to fined communication path. This paper conduct enhancing on VBF by Link Quality Estimation to enhance packet delivery ratio, end to end delay and energy efficiency. The simulation was done and we fined regarded enhancement in these terms.
