ATEMU: a fine-grained sensor network simulator
The design and implementation of ATEMU, a fine grained sensor network simulator that adopts a hybrid strategy, where the operation of individual sensor nodes is emulated in an instruction by instruction manner, and their interactions with each other via wireless transmissions are simulated in a realistic manner.

Adaptive Data Broadcast in Hybrid Networks
A technique that uses the broadcast medium for storage of frequently requested data, and an algorithm that continuously adapts the broadcast content to match the hot-spot of the database is described, which can be accurately obtained by monitoring the "broadcast misses" observed through direct requests.

Modeling and control of hysteresis in magnetostrictive actuators
A novel dynamic model is proposed for the hysteresis in magnetostrictive actuators by coupling a Preisach operator to an ordinary differential equation, and a parameter identification method isExpand
On trust models and trust evaluation metrics for ad hoc networks
This work uses the theory of semirings to show how two nodes can establish an indirect trust relation without previous direct interaction, and shows that the semiring framework is flexible enough to express other trust models, most notably PGP's Web of Trust. Expand
A Probabilistic Emergent Routing Algorithm for Mobile Ad Hoc Networks
This paper takes a novel approach to the routing problem in MANETs by using swarm inteligenceinspired algorithms that uses Ant-like agents to discover and maintain paths in a MANET with dynamic topology. Expand
Physical-Layer Authentication
A general analysis and design framework for authentication at the physical layer where the authentication information is transmitted concurrently with the data by superimposing a carefully designed secret modulation on the waveforms is introduced. Expand
Trust evaluation in ad-hoc networks
This work shows how two nodes can establish an indirect trust relation without previous direct interaction using the theory of semirings, and gives intuitive requirements for any trust evaluation algorithm. Expand

This paper addresses recursive identification and adaptive inverse control of hysteresis in smart material actuators, where hystereresis is modeled by a Preisach operator with a piecewise uniform density function. Expand
On Trust Establishment in Mobile Ad-Hoc Networks
It is argued that peer-to-peer networks are especially suitable to solve the problems of generation, distribution, and discovery of trust evidence in mobile ad-hoc networks, and the importance of evaluation metrics in trust establishment is illustrated. Expand
A framework for MAC protocol misbehavior detection in wireless networks
This work casts the fundamental problem of detection of node misbehavior at the MAC layer within a minimax robust detection framework, and shows that the ideas can be extended to the case where observations are hindered by interference due to concurrent transmissions. Expand
