Discrete abstractions of hybrid systems
It is shown that interesting classes of hybrid systems can be abstracted to purely discrete systems while preserving all properties that are definable in temporal logic. Expand
ATPC: Adaptive Transmission Power Control for Wireless Sensor Networks
ATPC is presented, a lightweight algorithm for Adaptive Transmission Power Control in wireless sensor networks that employs a feedback-based transmission power control algorithm to dynamically maintain individual link quality over time and is robust even with environmental changes over time. Expand
Flocking in Fixed and Switching Networks
This note analyzes the stability properties of a group of mobile agents that align their velocity vectors, and stabilize their inter-agent distances, using decentralized, nearest-neighbor interactionExpand
Robustness of temporal logic specifications for continuous-time signals
This paper proposes multi-valued semantics for MTL formulas, which capture not only the usual Boolean satisfiability of the formula, but also topological information regarding the distance, @e, from unsatisfiability. Expand
A Framework for Worst-Case and Stochastic Safety Verification Using Barrier Certificates
This paper presents a methodology for safety verification of continuous and hybrid systems in the worst-case and stochastic settings, and computes an upper bound on the probability that a trajectory of the system reaches the unsafe set, a bound whose validity is proven by the existence of a barrier certificate.

Temporal-Logic-Based Reactive Mission and Motion Planning
This paper provides a framework to automatically generate a hybrid controller that guarantees that the robot can achieve its task when a robot model, a class of admissible environments, and aExpand
Optimal paths in weighted timed automata
An algorithm to solve the optimal-reachability problem for weighted timed automata that takes time exponential in O(n), where n is the number of clocks, |δ(A)| is the size of the clock constraints and |W max | is thesize of the largest weight. Expand
Stable flocking of mobile agents, part I: fixed topology
This first part generates stable flocking motion for the group using a coordination control scheme which gives rise to smooth control laws for the agents, ensuring collision avoidance and cohesion of the group and an aggregate motion along a common heading direction. Expand
Approximation Metrics for Discrete and Continuous Systems
This paper develops the first framework of system approximation that applies to both discrete and continuous systems by developing notions of approximate language inclusion, approximate simulation, and approximate bisimulation relations and defines a hierarchy of approximation pseudo-metrics between two systems.

Conflict resolution for air traffic management: a study in multiagent hybrid systems
The method models the aircraft and the manoeuvre as a hybrid control system and calculates the maximal set of safe initial conditions for each aircraft so that separation is assured in the presence of uncertainties in the actions of the other aircraft. Expand
