Method and apparatus for multi-network communication in vehicular networks
First Claim
1. A mobile wireless network data router configured to connect vehicles to an Internet infrastructure through a multi-technology network device;
- wherein the router is configured to form a mesh network of vehicles connected to the infrastructure,wherein the router is configured to redistribute a Wi-Fi signal from a fixed hotspot among a plurality of parked vehicles, andwherein a expected contact time between the network data router of a vehicle i and a reachable network j of another vehicle or Wi-Fi hotspot or roadside unit (“
RSU”
), is derived from a formula comprising;
