In this paper, based on approved traffic flow distributions, we develop analytical expressions for Vehicular Ad Hoc Network (VANET) connectivity with respect to the number of reachable neighbors. Node mobility is accounted for by assuming probabilistic disturbance events that instantaneously disrupt the connection between nodes. Next, the lower bound of(More)
—We study how to achieve optimal network capacity in the most energy-efficient manner over a general large-scale wireless network, say, a multi-hop multi-radio multi-channel (MR-MC) network. We develop a multi-objective optimization framework for computing the resource allocation that leads to optimal network capacity with minimal energy consumption. Our(More)
—Vehicle-to-vehicle (V2V) communication networks, as one of the core components in connected vehicle systems, have been granted many promising applications to address traffic mobility, safety and sustainability. However, only a limited amount of work has been completed to understand the fundamental properties of information propagation in such systems,(More)
In this work, we study a system of parabolic inequalities. Using the method of test functions, we establish an integral estimate and get a Liouville-type theorem for the solutions of this system. As an application, we observe the well-known Fujita blow-up phenomena for the corresponding parabolic system. Here, the importance of this observation is that we(More)
