Network connectivity is a fundamental requirement for intervehicle communication and services in VANETs. The fast movement of the vehicles results in rapid changes in network topology generating dynamic variation in network connectivity, which causes

Let T∈ℕ with T>5. Let 𝕋:={1,…,T}. We study the Fučik spectrum Σ of the discrete problem Δ2u(t-1)+λu+(t)-μu-(t)=0, t∈𝕋, u(0)=u(T+1)=0, where u+(t)=max{u(t),0}, u-(t)=max{-u(t),0}. We give an expression of Σ via the matching-

As the key nodes in the vehicle ad hoc network (VANET) play a vital role in the dissemination of information, evaluating the importance of nodes is necessary. In this paper, based on Intelligent Driver Model with Lane Changes (IDM-LC), the VanetMobiS
