Network routing system, method, and computer program product

A system that relays data on a multi-hop network, the system comprising:

• a first cellular base station;
• a first relay device that relays first data between the first cellular base station and at least one cellular device via at least a first wireless communications channel and a second wireless communications channel, encrypts third data with a security key based on a security identifier associated with the first relay device to create encrypted third data, and transmits the encrypted third data to the first cellular base station over the first wireless communications channel;
• and
• a second cellular base station that obtains a measurement associated with operation of the first cellular base station and directs, while the first relay device is in communication with the at least one cellular device via at least the second wireless communications channel, the first relay device to change from connecting with the first cellular base station to connecting with the second cellular base station based at least in part on the measurement associated with operation of the first cellular base station, wherein the first relay device relays second data between the second cellular base station and the at least one cellular device after connecting to the second cellular base station.

Non-transitory computer-readable storage comprising instructions that, when executed, cause a method of relaying data on a multi-hop network to be performed, the method comprising:

• receiving first data at a first cellular base station in a multi-hop network from a first relay device via at least a first wireless communications channel, wherein the first relay device receives the first data from at least one cellular device via at least a second wireless communications channel;
• encrypting third data with a security key based on a security identifier associated with the first relay device to create encrypted third data;
• transmitting the encrypted third data from the first cellular base station to the first relay device;
• obtaining a measurement associated with operation of the first cellular base station;
• while the first relay device is in communication with the at least one cellular device via at least the second wireless communications channel, directing the first relay device to change from connecting with the first cellular base station to connecting with a second cellular base station based at least in part on the measurement associated with operation of the first cellular base station;
• and
• after the directing, receiving second data at the second cellular base station from the first relay device via at least a third wireless communications channel, and wherein the first relay device is in communication with the second cellular base station via at least the third wireless communications channel.
