Server less distributed computing has received significant attention from both the business and the investigate society. Among the most popular applications are the wide-area network file systems, exemplified by CFS, Farsite, and Ocean Store. These file systems store files on a large collection of untrusted nodes that form an overlay network. They use cryptographic techniques to maintain file c...

IPv6 as IP next generation is the successor to IPv4. IPv6 not only solves the shortcomings problem of IPv4 address, but also benefits the QoS especially during network congestion. Flow label field in IPv6 packet header provides an efficient way for packet marking, flow identification, and flow state lookup. This paper proposes the end-to-end QoS provisioning mechanism by utilizing 3-tuple inste...

The heterogeneity of today’s computing environment means computation-intensive signal processing algorithms must be optimized for performance in a machine dependent fashion. In this paper, we present a dynamic memory model and associated optimization framework that finds a machine-dependent, near-optimal implementation of an algorithm by exploiting the computation-memory tradeoff. By optimal, w...

TOPLUS is a lookup service for structured peer-to-peer networks that is based on the hierarchical grouping of peers according to network IP prefixes. In this paper we present MULTI+, an application-level multicast protocol for content distribution over a peer-to-peer (P2P) TOPLUS-based network. We use the characteristics of TOPLUS to design a protocol that allows for every peer to connect to an...

A novel architecture is proposed for future multi-terabit IP (internet protocol) routers, employing multiple cascaded stages of optical switching and buffering. WDM is used within the node to facilitate its operation. External synchronization is not required, and a void-filling algorithm is used to simplify hardware requirements. Packet priorities are not implemented in the current version of t...

Name-based routing belongs to a routing category different from address-based routing, it is usually adopted by content-oriented networks [Sharma et al., 2014, Koponen et al., 2007, Rajahalme et al.,2011, Thaler et al.,1998, Hwang et al., 2010, Gritter et al., 2001, Caesar et al., 2006, Carzaniga et al., 2004, Koponen et al., 2007, Hwang et al., 2009 Singla et al., 2010, Detti et al., 2011, Jai...

Sensor network is a novel technology about acquiring and processing information. This paper introduces the basic interaction patterns between requesters and providers of services during a typical Service Discovery task. It discusses existing service discovery protocols and provides a preliminary analysis of the mechanisms for service and resource discovery in the Wireless Sensor Network domain....

In this work, we optimally solve the problem of multiplierless design second-order Infinite Impulse Response filters with minimum number adders. Given a frequency specification, stable direct form filter hardware-aware fixed-point coefficients that yielding minimal adders when replacing all multiplications by bit shifts and additions. The coefficient design, quantization implementation, typical...

Overlay networks are networks operating on the inter-domain level, where the edge hosts learn of each other and, based on knowledge of underlying network performance, they form loosely coupled neighboring relationships. These relationships can be used to induce a specific graph, where nodes are representing hosts and edges are representing neighboring relationships. Graph abstraction and the as...
