slugSubterranean Decibal Networks of AUVs by Adopting Location Conscious Source Routing
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 4
Abstract
Acoustic networks of autonomous underwater vehicles cannot typically rely on protocols intended for terrestrial radio networks. Therefore a new location - aware source routing (LASR) protocol is shown to provide superior network performance over two commonly used network protocols = flooding and dynamic source routing (DSR). LASR includes an improved l ink/route metric and a node tracking system. LASR greatly increases performance compared to DSR.LASR includes a tracking system that predicts node locations, so that LASR can proactively respond totopology changes. LASR delivers 2 - 3 times as many messages as flooding in 72% of the simulated missions and delivers 2 – 4 times as many messages as DSR in 100% of the missions. In 67% of the simulated missions, LASR delivers messages requiring multiple hops to cross the network with 2 – 5 times greater reliability th an flooding or DSR.
