Jammer-Assisted Resource Allocation in Secure OFDMA With Untrusted Users
[article]
2019
arXiv
pre-print
Preserved Fulltext
In this paper, we consider the problem of resource allocation in the orthogonal frequency division multiple access system with single source and M untrusted users in presence of a friendly jammer. ...
Next, we consider fair resource allocation by introducing a novel concept of subcarrier snatching with the help of jammer. ...
In contrast, secure OFDMA with untrusted users in the absence of jammer has in general no other option but to allocate a subcarrier to its best gain user. ...

In this paper, we consider a cooperative orthogonal frequency division multiple access (OFDMA) system, where a source communicates with multiple users with the help of an untrusted relay. ...
With the aim of maximizing the weighted sum secrecy rate, we formulate a joint resource allocation problem of power allocation, subcarrier assignment and subcarrier pairing. ...
However, joint resource allocation in secure cooperative OFDMA system with untrusted relay poses new challenges which have not yet been investigated.
