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)
Multi-tenant data centers provide a cost-effective many-server infrastructure for hosting large-scale applications. These data centers can run multiple virtual machines (VMs) for each tenant, and potentially place any of these VMs on any of the servers. Therefore, for inter-VM communication, they also need to provide a VM resolution method that can quickly… (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)
—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)
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)
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.
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)
—Pipelines are widely used to increase throughput in multi-core chips by parallelizing packet processing. Typically, each packet type is serviced by a dedicated pipeline. However, with the increase in the number of packet types and their number of required services, there are not enough cores for pipelines. In this paper, we study pipeline sharing, such… (More)
