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...
To effectively address the explosive growth of multimedia applications over the Internet, a large-scale media streaming system has to fully take into account the issues of security, quality of service (QoS), scalability, and heterogeneity. However, current streaming solutions do not address all these challenges simultaneously. To address this limitation, this paper proposes a secure and high-performance...
