A++ Random Access for Two-Way Relaying in Wireless Networks
Published:2012-12-09 Hit:743

 

Overview:

Two-way relaying can significantly improve performance of next generation wireless networks. However, due to its dependence on multi-node cooperation and transmission coordination, applying this technique to a wireless network in an effective and scalable manner poses a challenging problem. To tackle this problem without relying on complicated scheduling or network optimization algorithms, we propose a scalable random access scheme that takes measures in both the physical layer and the medium access control layer. Specifically, we propose a two-way relaying technique that supports fully asynchronous transmission and is modulation-independent. On the top of this new physical layer technique, a random access MAC protocol, called A++, is designed to dynamically form two-way relaying cooperation in a wireless network with Asynchronous transmission and Asymmetrical flows.
