Reduction of Scanning Reporting Overhead in IEEE 802.16 Networks with Relays

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%.
