Abstract
The present invention relates to a method for allocating transfer times of a low degree of complexity for improving physical-layer security in a wireless powered communication network. A method for allocating transfer times in a wireless powered communication network according to an embodiment of the invention can provide a low-complexity method of allocating transfer times that enables physical-layer security in a secure wireless powered communication network (WPCN) using an energy harvesting jammer, and this method can be utilized to establish an energy harvesting communication system that is efficient in terms of information security.
Claims6
A method for allocating transfer times in a wireless powered communication network using an energy harvesting jammer, the method comprising:
- obtaining frequency band information;
- obtaining an upper limit for a secrecy rate;
- obtaining first channel state information and second channel state information relating to an energy transfer operation, the first channel state information representing energy transferred by a hybrid access point to a user during the energy transfer operation, the second channel state information representing energy transferred by the hybrid access point to a jammer during the energy transfer operation;
- obtaining third channel state information, fourth channel state information, first channel distribution, and second channel distribution relating to an information transfer operation, the third channel state information representing information transferred by the user to the hybrid access point during the information transfer operation, the fourth channel state information representing information transferred by the jammer to the hybrid access point during the information transfer operation, the first channel distribution representing information transferred by the user to a tapper, and the second channel distribution representing jamming signals transferred by the jammer to the tapper;
- and
- calculating times allocated to the energy transfer operation and the information transfer operation based on the frequency band information, the upper limit for a secrecy rate, the first channel state information, the second channel state information, the third channel state information, the fourth channel state information, the first channel distribution, and the second channel distribution such that a secrecy outage probability is minimized.
