Token flow control

by Amit Kumar, et al.
"... As companies move towards many-core chips, an efficient onchip communication fabric to connect these cores assumes critical importance. To address limitations to wire delay scalability and increasing bandwidth demands, state-of-the-art on-chip networks use a modular packet-switched design with route ..."

with routers at every hop which allow sharing of network channels over multiple packet flows. This, however, leads to packets going through a complex router pipeline at every hop, resulting in the overall communication energy/delay being dominated by the router overhead, as opposed to just wire energy/delay

Energy-delay tradeoffs in smartphone applications

by Moo-ryong Ra, Jeongyeup Paek, Abhishek B. Sharma - In ACM MobiSys , 2010
"... Many applications are enabled by the ability to capture videos on a smartphone and to have these videos uploaded to an Internetconnected server. This capability requires the transfer of large volumes of data from the phone to the infrastructure. Smartphones have multiple wireless interfaces – 3G/EDG ..."
Abstract - Cited by 60 (0 self) - Add to MetaCart
of these applications are often naturally delay-tolerant, so that it is possible to delay data transfers until a lower-energy WiFi connection becomes available. In this paper, we present a principled approach for designing an optimal online algorithm for this energy-delaytradeoff usingthe

Energy-Delay tradeoff for data collection

by Shuguang Cui, Ritesh Madan, Andrea J. Goldsmith, Sanjay Lall - Proc. of IEEE Intl. Conf. on Communications (ICC), Seoul, Korea , 2005
"... Abstract — We consider a wireless sensor network where the nodes have limited energy. We first analyze the delay performance of a transmission scheme based on time division multiple access (TDMA). We propose a simple link scheduling algorithm to find the minimum-delay schedule given the slot lengths ..."

Power-Aware Routing in Mobile Ad Hoc Networks

by Mike Woo, Suresh Singh, C. S. Raghavendra , 1998
"... In this paper we present a case for using new power-aware metrics for determining routes in wireless ad hoc networks. We present five different metrics based on battery power consumption at nodes. We show that using these metrics in a shortest-cost routing algorithm reduces the cost/packet of rout ..."

/packet of routing packets by 5-30% over shortest-hop routing (this cost reduction is on top of a 40-70% reduction in energy consumption obtained by using PAMAS, our MAC layer protocol). Furthermore, using these new metrics ensures that the mean time to node failure is increased significantly. An interesting

A message ferrying approach for data delivery in sparse mobile ad hoc networks

by Wenrui Zhao, Mostafa Ammar, Ellen Zegura - In Proc. of ACM Mobihoc , 2004
"... Mobile Ad Hoc Networks (MANETs) provide rapidly deployable and self-configuring network capacity required in many critical applications, e.g., battlefields, disaster relief and wide area sensing. In this paper we study the problem of efficient data delivery in sparse MANETs where network partitions ..."

can last for a significant period. Previous approaches rely on the use of either long range communication which leads to rapid draining of nodes ’ limited batteries, or existing node mobility which results in low data delivery rates and large delays. In this paper, we describe a Message Ferrying (MF

Data Gathering in Sensor Networks using the Energy*Delay Metric

by Stephanie Lindsey, Cauligi Raghavendra, Krishna Sivalingam , 2001
"... In this paper we consider the problem of data collection from a sensor web consisting of N nodes, where nodes have packets of data in each round of communication that need to be gathered and fused with other nodes' packets into one packet and transmitted to a distant base station. Nodes have po ..."

power control in their wireless communications and can transmit directly to any node in the network or to the base station. With unit delay cost for each packet transmission, if all nodes transmit data directly to the base station, then both high energy and high delay per round will occur. In our prior

Optimizing the Energy-Delay-Ringing Product in On-Chip

by Cmos Line Drivers, Soroush Abbaspour, Massoud Pedram
"... Abstract- This paper presents a detailed empirical study and analytical derivation of voltage wave-form and energy dissipation of global lines driven by CMOS drivers. It is shown that at high clock frequencies where the output voltage at the termination point of the transmission line may not reach i ..."
Abstract - Add to MetaCart
, we propose a new design metric which is the product of energy, delay and some measure of ringing in lossy transmission lines. In particular, this paper provides closed-form expressions for the energy dissipation, 50 % propagation delay and the percentage of maximum undershoot when the circuit

"... This paper first presents an accurate and efficient method of estimating the short circuit energy dissipation and the output transition time of CMOS buffers. Next the paper describes a sizing method for tapered buffer chains. It is shown that the first-order sizing behavior, which considers only the ..."
