This paper presents a distributed algorithm for detecting deadlocks in the OR request model in distributed systems. The initiator of the algorithm builds a reduced local wait-for graph to determine a deadlock by employing two phases for probe propagation and receiving replies. The proposed algorithm exhibits faster deadlock detection and shorter blocked(More)
Many studies on reverse skyline query processing have been done for various services. The existing reverse skyline query processing methods are based on dynamic skylines. There are no reverse skyline query processing algorithms based on metric spaces for location-based services. The existing methods for processing a reverse skyline query have the limitation(More)
