An Incremental Hausdorff Distance Calculation Algorithm
The Hausdorff distance is commonly used as a similarity measure between two point sets. Using this measure, a set X is considered similar to Y iff every point in X is close to at ...

Prolonging Network Lifetime via a Controlled Mobile Sink in Wireless Sensor Networks
In this paper we explore the mobility of a mobile sink in a wireless sensor network (WSN) to prolong the network lifetime. Since the mechanical movement of mobile sink is driven by...
