Due to environmental concerns and strict constraints on interference imposed on other networks, the radiated power of emerging pervasive wireless networks needs to be strictly limited, yet without sacrificing acceptable data rates. Pulsed Time-Hopping Ultr ...

One of the key trends in computing over the past two decades has been increased distribution, both at the processor level, where multi-core architectures are now the norm, and at the system level, where many key services are currently distributed overmulti ...
This paper focuses on the design of an asynchronous broadcast primitive on the Intel SCC. Our solution is based on OC-Bcast, a state-of-the-art k-ary tree synchronous broadcast algorithm that leverages the parallelism provided by on-chip Remote Memory Acce ...
Concurrent implementations of abstract types usually rely on lock-free primitives or locks and are highly tuned to support a finite set of efficient operations. However, it is very hard to extend such types for specific needs by adding new operations. The ...
Many problems in distributed computing are impossible to solve when no information about process failures is available. It is common to ask what information about failures is necessary and sufficient to circumvent some specific impossibility, e. g., consen ...
Achieving sub-millisecond response times in a managed language environment such as Java introduces significant implementation challenges. The Achilles' heel of Java is its reliance on automatic memory management for reclaiming dead objects. Typically, the ...

This thesis studies communication and agreement protocols in wireless ad hoc networks from both theoretical and practical perspectives. The last decade has given rise to the rapid growth of wireless telecommunications such as cellular mobile phone networks ...

This paper defines the fault-tolerant mutual exclusion problem in a message-passing asynchronous system and determines the weakest failure detector to solve the problem. This failure detector, which we call the trusting failure detector, and which we denot ...

We consider the design of the MAC layer for low power, low data-rate, impulse-radio ultra-wide band (IR-UWB) networks. In such networks, the primary concern is energy consumption rather than rate efficiency. We explore several dimensions such as power cont ...
