Item Collaborative Neighbor Discovery with Slow Scan for Directional Sensor Networks(IEEE, 2018) Gudino, Lucy J.Neighbor discovery forms a vital part of Medium Access Control (MAC) and routing protocols in Directional Sensor Network (DSN). Discovering neighbors in DSN is a challenging task due to limited coverage of directional antennae. The Collaborative Neighbor Discovery (COND) protocol suggests a time-efficient mechanism to discover neighbors but fails to discover all the neighbors. In this paper, we propose an improvement over COND protocol by employing Slow-Scan (SS) mode, which sets different nodes in SS mode at different time intervals. This model named COllaborative Neighbor Discovery with Slow Scan (COND-SS) aims to discover all the nodes in the network. The simulation results reveal that the COND-SS protocol has lower latency and it improves the neighbor discovery ratio considerably up to 100%.
