Abstract: An electronic device able to communicate using both a long-range and a short-range wireless communication technology. A transceiver of the electronic device switches its operation mode based on a power saving mode of the long-range wireless communication technology. In particular, the electronic device switches between a short-range mode and a long-range mode based on the power saving mode of the long-range communication technology.

Abstract: An outdoor lighting network (OLN) is disclosed as a supplementary or contingency communications infrastructure for smart city systems. The OLN may integrate light points within the network as receivers which are switched from a standard OLN communication protocol to a D2D based protocol upon disruption of a primary smart city systems communications network, wherein each communication protocol includes a respective message prioritization method. Aspects of the disclosure additionally includes methods and apparatus for implementing an outdoor lighting network which can act, in cases of primary communication failure, as a D2D network in order to pass messages from smart city system field devices, through the converted D2D OLN network and to a smart city system central manager for proper handling and distribution of the smart city system field device communications.

Abstract: A system and method for enabling secure device-to-device (D2D) communication between a plurality of user devices. The method includes providing public and private keys for each of the user devices, the private key arranged to decrypt data encrypted by the corresponding public key. A sender user device creates a digital signature using its private key. The sender double-encrypts a transmission using both the public keys of a recipient user device and a first relay user device. The transmission is transmitted from the sender to the recipient through a plurality of relay user devices. Each relay user device receives the transmission, decrypts a first layer of encryption with its private key, encrypts the transmission with the public key of a subsequent user device; and forwards the data transmission to the subsequent user device. The recipient authenticates the digital signature of the sender using the public key of the sender.
