Joint Power Allocation at the Base Station and the Relay for Untrusted Relay Cooperation OFDMA Network
The secure communication that multiple OFDMA-based cell-edge mobile stations (MS) can only transmit confidential messages to base station (BS) through an untrusted intermediate relay (UR) is discussed. Specifically, with the destination-based jamming (DBJ) scheme and fixed MS transmission power assumption, our focus is on the joint BS and US power allocation to maximize system sum secrecy rate....
متن کاملResource Allocation for an OFDMA Relay Network with Multicells
In this paper, we propose a new subcarrier allocation algorithm for a downlink OFDMA relay network with multicells. In the proposed algorithm, subcarriers are allocated to users and relays to maximize the overall sum of the achievable rate under fairness constraints. Simulation results show that the proposed algorithm achieves higher data rate than the static algorithm and reduces the outage pr...
متن کاملCooperative Relay Based Resource Allocation for OFDMA Network
Cooperative relaying is a promising technique for Long Term Evolution Advanced (LTE-A) networks to satisfy high throughput demand and support heterogeneous communication services with diverse quality-of-service (QoS) requirements. Optimal relay selection, power allocation and sub carrier assignment scheme under a total power constrain is proposed for a Qos aware resource allocation for multi us...
متن کاملJoint Resource Allocation in Secure OFDMA-Based Networks Taking a Base Station as a Two-Way Relay
Due to the broadcast nature of wireless media, all nodes in the coverage of a transmitter are capable of capturing its signals, thus wireless transmission is sensitive to wiretapping. Several existing schemes place an emphasis on secrecy rate improvement, under the protocols of amplify-and-forward or decode-and-forward, when there are only relay users in the network. We set up a novel communica...
متن کاملSubcarrier Allocation Algorithm for an OFDMA Relay Network with Multicells
In this paper, a new subcarrier allocation algorithm is proposed for an OFDMA relay network with multicells. In the proposed algorithm, subcarriers are allocated to users and relays so as to maximize the overall sum of the achievable rate under fairness constraints. Fairness constraints are imposed on the minimum rate requirement of users and the maximum power of base stations and relays. Simul...
