Novel Relay Selection Protocol for Cooperative Networks
share
Extensive research has been done to achieve better throughput and reliability in wireless networks, with focus on multiple-input multiple-output systems. Recently, cooperative networking techniques have been investigated to increase the performance of low-cost wireless systems by using the diversity created by different single antenna devices. However, cooperative networking requires a medium access control layer able to handle source-relay-destination communications. Wireless cooperative relaying poses several challenges, being the most important one related to the relay selection mechanism, especially in the presence of mobile nodes. This position paper aims to describe our findings towards development of an efficient relay selection algorithm.
