Feasibility Study of the Mesh Extension for the IEEE 802.16e Communication System

Abstract

The demand for wireless broadband access is rapidly growing. Consequently, the need for wireless systems offering both high speed data rates and high mobility access will become more and more important for present and future communication systems. An interesting candidate to fulfill those requirements is the OFDMA-based IEEE 802.16e wireless metropolitan area network system. In this paper, we study the possible implementation of the Mesh topology for the IEEE 802.16e standard. The reuse of the TDD frame structure considered in the point-to-multipoint topology will be discussed. The performance of the OFDMA air interface will be analyzed, for a varying spectral reuse factor and for different carrier allocations amongst the users.

An Integrated Routing and Scheduling Approach for Persistent Vehicle Communication in Mobile WiMAX Mesh Networks

“…In PMP mode frames are separated for uplink and downlink traffics; in mesh mode frames are separated for control and data traffics regardless of direction. In [8] and [14], efforts were made to realize the mesh mode frames under PMP mode operation.…”

“…The mesh mode, on the other hand, is only supported by OFDM according to the standard. In [8] and [14], efforts were made to realize the OFDMA physical layer for supporting the mesh mode frame structure. …”
