Macrocell Label Switching Mechanism for MPLS-WiMAX Networks

Abstract

This paper proposes a fast macrocell label switching mechanism (MLSM) in the MPLS-WiMAX networks. The mobil station (MS) communicates with each other within macrocell, e.g., MSA in the cellA communicates with MSB in the other cell, and can be switched via the media access control (MAC) layer without involving the network layer. The average access delay of request from MSs is studied and analyzed in this paper. Finally, simulation results show that the purposed MLSM operates effectively and efficiently in terms of network throughput, average delay, and resource utilization.
