New Schema for Admission Control in WIMAX Relay Station Mesh Network for Mobile Stations out of Coverage Using Ad-Hoc

WIMAX has been approved by IEEE 802.16 as a standard to provide a highly data rate transmission, This paper describe a problem in the mesh network relay station, for instance the problem of how to serve the mobile stations (MSs) which are out of the base station (BS) and relay station coverage. This paper also proposed a solution for mobile stations out of the coverage of the WIMAX relay stations mesh network. Therefore ad-hoc network defined as a solution by using its admission control scheme and apply it on the mobiles inside and outside the relay station coverage.
