An Efficient Cooperative Media Access Control Based Relay Node Selection in Wireless Networks

Relay Node Selection Algorithm for Cooperative Communications in Wireless Networks

IEEE 802.11a/b/g standards support multiple transmission rates. Even though the use of multiple transmission rates increase the WLAN capacity, this feature leads to the performance anomaly problem. Cooperative communication was introduced to relieve the performance anomaly problem. Data packets are delivered to the destination much faster through a relay node with high rate than through direct ...

Cooperative Diversity in Wireless Networks: Relay Selection and Medium Access

Resource-Efficient Relay Selection in Cooperative Wireless Networks

This thesis focuses on cooperative relaying protocols employing a relay node that overhears data transmissions between a source and a destination nodes and retransmits the data when necessary. The achieved signal diversity at the destination improves the data recovery in fading-rich environments. While cooperative relay can improve communication on one link, the induced relay interference can d...

Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
