A monitoring of signal quality must be performed in wireless networks since the users are continuously moving among base or relay stations. This is done via so called scanning procedure when a mobile station measures specific channel parameters. After each scanning, the mobile station reports the results to its serving station. This paper proposes a new method for delivering of scanning results to the serving base station if relay stations are deployed in network. The main goal of the proposal is to design a reporting technique that generates minimum management overhead during reporting. This is achieved by collecting of individual MSs’ results into one message in access station. The results show reduction of scanning reporting management overhead up to 30%.
