A management system for a fleet of material handling vehicles, the management system comprising: a management server system (20, 22) enabled for communication over a management network (22, 24, 30); a first material handling vehicle and a second material handling vehicle (50a, 50b, 50c, 50d), each including a processor device and a communication device, wherein the first material handling vehicle is configured to form part of a mesh network with a plurality of other material handling vehicles (50a, 50b, 50c, 50d); the processor device of the first material handling vehicle being configured to: communicate, via the mesh network, with at least one of the management server system and the second material handling vehicle; determine that the second material handling vehicle (50a, 50b, 50c, 50d) is in proximity to the first material handling vehicle; obtain a second-vehicle vehicle identification from the second material handling vehicle (50a, 50b, 50c, 50d); based upon the second-vehicle vehicle identification, determine whether the second material handling vehicle (50a, 50b, 50c, 50d) is a missing vehicle; based upon determining that the second material handling vehicle (50a, 50b, 50c, 50d) is a missing vehicle, wherein a missing vehicle is a vehicle that is in a location that is unknown to the management server system (20, 22) or is not in communication with the management server system (20, 22), execute control over a function of the second material handling vehicle (50a, 50b, 50c, 50d), wherein controlling the function of the second material handling vehicle includes at least one of: stopping operation of one or more systems of the second material handling vehicle (50a, 50b, 50c, 50d); and preventing an operator from executing one or more operations on the second material handling vehicle (50a, 50b, 50c, 50d). a management server system (20, 22) enabled for communication over a management network (22, 24, 30); a first material handling vehicle and a second material handling vehicle (50a, 50b, 50c, 50d), each including a processor device and a communication device, wherein the first material handling vehicle is configured to form part of a mesh network with a plurality of other material handling vehicles (50a, 50b, 50c, 50d); the processor device of the first material handling vehicle being configured to: communicate, via the mesh network, with at least one of the management server system and the second material handling vehicle; determine that the second material handling vehicle (50a, 50b, 50c, 50d) is in proximity to the first material handling vehicle; obtain a second-vehicle vehicle identification from the second material handling vehicle (50a, 50b, 50c, 50d); based upon the second-vehicle vehicle identification, determine whether the second material handling vehicle (50a, 50b, 50c, 50d) is a missing vehicle; based upon determining that the second material handling vehicle (50a, 50b, 50c, 50d) is a missing vehicle, wherein a missing vehicle is a vehicle that is in a location that is unknown to the management server system (20, 22) or is not in communication with the management server system (20, 22), execute control over a function of the second material handling vehicle (50a, 50b, 50c, 50d), wherein controlling the function of the second material handling vehicle includes at least one of: stopping operation of one or more systems of the second material handling vehicle (50a, 50b, 50c, 50d); and preventing an operator from executing one or more operations on the second material handling vehicle (50a, 50b, 50c, 50d). communicate, via the mesh network, with at least one of the management server system and the second material handling vehicle; determine that the second material handling vehicle (50a, 50b, 50c, 50d) is in proximity to the first material handling vehicle; obtain a second-vehicle vehicle identification from the second material handling vehicle (50a, 50b, 50c, 50d); based upon the second-vehicle vehicle identification, determine whether the second material handling vehicle (50a, 50b, 50c, 50d) is a missing vehicle; based upon determining that the second material handling vehicle (50a, 50b, 50c, 50d) is a missing vehicle, wherein a missing vehicle is a vehicle that is in a location that is unknown to the management server system (20, 22) or is not in communication with the management server system (20, 22), execute control over a function of the second material handling vehicle (50a, 50b, 50c, 50d), wherein controlling the function of the second material handling vehicle includes at least one of: stopping operation of one or more systems of the second material handling vehicle (50a, 50b, 50c, 50d); and preventing an operator from executing one or more operations on the second material handling vehicle (50a, 50b, 50c, 50d). stopping operation of one or more systems of the second material handling vehicle (50a, 50b, 50c, 50d); and preventing an operator from executing one or more operations on the second material handling vehicle (50a, 50b, 50c, 50d).
