— We consider energy efficient packet forwarding with quality-of-service (QoS) guarantee for wireless sensor networks (WSNs). In most existing wireless network protocols, route ...
In this paper, we discuss and compare several policies to place replicas in tree networks, subject to server capacity constraints. The client requests are known beforehand, while ...
The Cell processor offers substantial computational power which can be effectively utilized only if application design and implementation are tuned to the Cell architecture. In th...
—In this paper, we consider multi-hop wireless mesh networks, where each router node is equipped with multiple radio interfaces and multiple channels are available for communicat...
Abstract. Many combinatorial optimization problems can be formulated as 0/1 integer programs (0/1 IPs). The investigation of the structure of these problems raises the following ta...
