Paper Accepted in Journal of King Saud University – Computer and Information Sciences

We are happy to announce that one of our papers titled “Low-cost relay selection in multihop cooperative networks”, has been accepted and published in “Journal of King Saud University – Computer and Information Sciences (Q1, Impact Factor: 6.9)“. This work was a joint collaboration between CCDS professors Dr. Md Zahangir Alam and Dr. Ashraful Islam and collaborators from Department of CSE, IUB. The paper can be read at

In this work, the authors presented algorithmic strategies to simplify a multihop parallel single-input single-output (SISO) relay network into a series multi-hop network by finding the best path having the maximum received signal-to-noise ratio (SNR). The best relay selection by using dynamic programming search entails high computations and large memory requirements, as well as involves the full CSI information, making this approach impractical for large-scale networks. The goal of the proposed low-cost near-optimal routing strategy in this work is to provide close to optimal performance with much less complexity compared to traditional routing.
