We address the problem of gathering information in sensor webs consisting of sensors nodes, where in a round of communication sensor nodes have messages to be sent to a distant central node (called the base station) over shortest path. There is a wide range of data gathering applications like: target and hazard detection, environmental monitoring,… (More)
—With the rise of datacenter virtualization, the number of entries in forwarding tables is expected to scale from several thousands to several millions. Unfortunately, such forwarding table sizes can hardly be implemented today in on-chip memory. In this paper, we investigate the compressibility of forwarding tables. We first introduce a novel forwarding… (More)
—With the rise of datacenter virtualization, the number of entries in the forwarding tables of datacenter switches is expected to scale from several thousands to several millions. Unfortunately, such forwarding table sizes would not fit on-chip memory using current implementations. In this paper, we investigate the compressibility of forwarding tables. We… (More)
Wireless sensor networks represent a new generation of real time traffic communications and high data rate sensor applications, such as structural health monitoring and control. We study some problems related to data gathering in sensor networks when the information that the sensors collect about their environment must be delivered to a collecting central… (More)
Many-to-one packet routing and scheduling are fundamental operations of sensor networks. It is well known that many sensor network applications rely on data collection from the nodes (the sensors) by a central processing device. There is a wide range of data gathering applications like: target and hazard detection, environmental monitoring, battlefield… (More)
experimental evaluation shows that a large number of paths can be utilized when running the multi-path protocols over the internet, and thus that our multi-path approach can be effectively deployed over existing IP networks.
—Fault Management (FM) is a cardinal feature in communication networks. One of the most common FM approaches is to use periodic keepalive messages. Hence, switches and routers are required to transmit a large number of FM messages periodically, requiring a hardware-based packet generator that periodically transmits a set of messages that are stored in an… (More)
