Most of the previous studies on scientific collaborator recommendation are based on social proximity analysis to suggest collaborators. However, the extracted homogeneous features cannot well represent the multiple factors which may implicitly affect the future scientific collaboration. In this paper we propose an approach based on the multiple heterogeneous network features, which has produced good...
BitTorrent has generated a significant and continuously increasing portion of Internet traffic. Several designs have been recently proposed to reduce the BitTorrent traffic without sacrificing user downloading performance. However, Most of these designs only consider IPv4-only Internet, not thinking about IPv4/IPv6 hybrid network. With the exhaustion of IPv4 addresses and the development of IPv6,...
In wireless sensor networks (WSNs), QoS topology control achieves energy-efficiency by turning off redundant nodes and links, while still satisfying the given QoS requirement. However, existing topology control algorithms assume that links are either connected or disconnected. Recent experiments have shown that, besides the connected and disconnected region, a large percentage of links reside in the...
In mobile sensor networks, the mobility of nodes leads to frequent changes of network topology, therefore the communication links between source nodes and sink vary dynamically. The receiver based routing protocols do not need to establish global routing between source nodes and sink, but allow the neighbor nodes of the sender to contend for the forwarding right under certain rules, and only the contention...
Clustering approach is one of the most used routing methodologies for wireless sensor network. However, most of the clustering practices make use of greedy cluster head formation process, wherein each node broadcasts its interest in becoming cluster head which is both energy and network intensive. In this paper we present a mechanism for efficient clustering formation, wherein an optimal number of...
