Delay Optimization-Based Joint Route Selection and Resource Allocation Algorithm for Cognitive Vehicular Ad Hoc Networks (Workshop)

摘要: Cognitive vehicular ad-hoc networks (CVANETs) are expected to improve spectrum utilization efficiently and offer both infotainment safety services for vehicles. In this paper, the joint route selection resource allocation problem is considered CVANETs. Taking into account lifetime of transmission links, we first propose a candidate link method which selects links satisfying constraint. Then stressing importance delay, formulate as an end-to-end delay minimization problem. As formulated optimization complicated integer nonlinear problem, cannot be solved conveniently, equivalently transform original two subproblems, i.e., subproblem subproblem. Solving subproblems by applying K shortest path algorithm Dijkstra algorithm, respectively, can obtain strategy. Simulation results demonstrate effectiveness proposed algorithm.
