At present, there are many problems in infrared technology of the near-field smart meter reading, such as being easily interfered by light, low transmission rate, long meter reading time, short operating distance and so on. To above issues, this paper presents a technical scheme of field meter reading based on Bluetooth technology and broadband carrier instead of infrared technology, and designs an...
Privacy protection has been in intensive concerns in Location Based Service (LBS). In existing research, tremendous efforts have been brought to obfuscation techniques and developing new anonymity to preserve the location privacy. However, these techniques may either sacrifice the service accuracy or rely on a trusted third party. To deal with this, in this paper, we propose a decentralized data forwarding...
Streaming services are gaining popularity and have contributed a tremendous fraction of today's cellular network traffic. Both playback fluency and battery endurance are significant performance metrics for mobile streaming services. However, because of the unpredictable network condition and the loose coupling between upper layer streaming protocols and underlying network configurations, jointly optimizing...
This paper is concerned with the Gaussian relay channel (GRC) under the one-code constraint, where the source and the relay utilize the same code to send message. An advantage of such one-code constraint is that the error propagation resulting from re-encoding can be mitigated as the relay can forward directly the decoded “codeword” to the destination. The maximal achievable rate of the considered...
