- Information-Theoretic Multi-Hopping for Relay Networks
- Recent advances in multi-hopping are extended to relay networks having multiple antennas and multiple sources. As for the single-antenna and single-source case, one can achieve the ergodic capacity of wireless relay networks with phase fading if the relays are in a region near the source terminal, and if phase information...

- Abstracting C With abC
- A conceptually simple and practically very useful form of data abstraction in model checking is variable hiding, which amounts to suppressing all information about a given set of variables. The abC tool automates this for programs written in the C programming language. It features an integrated demand-driven pointer analysis, and...

- A Bandwidth Allocation Model With High Concurrence Rate in IEEE 802.16 Mesh Mode
- In this paper, a bandwidth allocation model is proposed for multi-hop Wireless Mesh Network (WMN) with a goal of achieving high traffic throughput in minimal scheduling time slots. Scheduling scheme based on the optimization model serves the centralized scheduling first and compresses the scheduling time to minimum by enhancing concurrence...

- Timed Spi-Calculus With Types for Secrecy and Authenticity
- This paper presents a discretely timed spi-calculus. A primitive for key compromise allows to model key compromise attacks, thus going beyond the standard Dolev-Yao attacker model. A primitive for reading a global clock allows the authors to express protocols based on timestamps, which are common in practice. The authors accompany...

- Characterizing Achievable Rates in Multi-Hop Wireless Mesh Networks With Orthogonal Channels
- This paper considers the problem of determining the achievable rates in multi-hop wireless mesh networks with orthogonal channels. The authors classify wireless networks with orthogonal channels into two types, half duplex and full duplex, and consider the problem of jointly routing the flows and scheduling transmissions to achieve a given...

- Precomputing High Quality Routes for Bandwidth Guaranteed Traffic
- This paper investigates the problem of precomputing bandwidth guaranteed paths as a cheaper replacement for on-demand routing. The focus in the prior precomputation literature has been on minimizing storage and computational overhead of the precomputation process. This paper instead explores the "quality" of precomputed paths and attempts to answer the...

- Complexity of Wavelength Assignment in Optical Network Optimization
- This paper studies the complexity of a spectrum of design problems for optical networks in order to carry a set of demands. Under Wavelength Division Multiplexing (WDM) technology, demands sharing a common fiber are transported on distinct wavelengths. Multiple fibers may be deployed on a physical link. The basic goal...

- ACACIA: A Certificate-Based Access-Controlled Internet Architecture
- The current Internet architecture supports open connectivity, i.e., any host can send traffic to any other host. This has resulted in a number of security problems such as Distributed Denial-of-Service (DDoS) attacks, worms etc. This paper proposes ACACIA - A Certificate-based Access-Controlled Internet Architecture. In ACACIA, a source must first...
