Abstract We study liveness and model checking problems for broadcast networks, a system of identical clients communicating via message passing. The first problem that we consider is Liveness Verification . It asks whether there computation such one visits final state infinitely often. complexity the has been open. was shown to be $$\texttt {P}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/...

Minimizing broadcast latency is one of the most important issues for broadcasting in duty-cycled wireless sensor networks. The existing broadcast schemes do not allow any collision in a schedule to ensure its completion, i.e. all nodes receive a broadcast message collision-freely. A delay of transmission caused by the collision-prevention may increase the broadcast latency if the delay occurs a...

The U.S. has set 2015 as a goal to reach grid parity (that point where solar electricity is equal to grid electricity) while other nations predict reaching it as soon as 2010. No matter your thoughts on regulatory involvement it is clear there will be a resurgence in investment, development and innovation within the PV manufacturing community throughout the world and it will largely be driven b...
