Recent Study on Location Verification Based Neighbor Discovery for Shortest Routing in Underwater Acoustic Sensor Network

Under water acoustic sensor network is currently analyzing by the researchers in term of energy efficiency, shortest routing and improving throughput. Neighbor discovery is one of the most important tasks in shortest secure routing in UASN. The main objective of this paper is to discover a shortest route by connecting trusted nodes in terms of location. The location information sent by the node is verified by Al-Wahda approach for assigning the node as the best nearest neighbor node. Since the intermediate nodes are best neighbors in terms of location and trust value, the efficacy of the routing is high. The performance of the neighbor discovery is analyzed using multi-hop settings. There will be an upper and lower bound value is assigned for routing from source to destination. Our neighbor discovery algorithms do not require estimates of node density and allow asynchronous operation .The simulation for this paper is carried out in Network Simulator software and the performance is evaluated.
