To improve performance, large-scale Internet systems require clients to access nearby servers. While centralized systems can leverage static topology maps for rough network distan...
In a Distributed Database System (DDBS), transactions on objects can be read requests or write requests in a random manner. The replication algorithm of objects critically affects...
—Emerging applications of wireless sensor networks (WSNs) require real-time quality of service (QoS) guarantees to be provided by the network. However, designing real-time schedu...
This paper presents an approach for exchanging presence information between users of an instant messaging system in a mobile ad hoc network. As major feature, presence information ...
Abstract. Current research in peer to peer systems is lacking appropriate environments for simulation and experimentation of large scale overlay services. This has led to a plethor...
