Bidirectional Relaying in Wireless Networks - Impact of Degree of Coordination
Document Actions
The concept of bidirectional relaying is a key technique to improve the performance in wireless networks as sensor, ad-hoc, and even cellular systems. It is specified by a three-node network, where a relay node establishes a bidirectional communication between two other nodes using a decode-and-forward protocol. We assume that the communication is disturbed by unknown varying interference and analyze the impact of the degree of coordination. It shows that the unknown variation of the interference has a dramatic impact on the communication. For traditional interference coordination it can lead to channels which completely prohibit any reliable communication. Anyhow, by allowing a relay-to-receivers coordination, communication can also be established in such situations where the traditional approach fails.
