  Abstract

In this paper, a new handover procedure for OFDM-based mobile wireless mesh networks is proposed to reduce the handover overhead by distinguishing inter-cluster handover event from intra-cluster handover event and selecting MR with minimum path at the level of physical layer using a hierarchical design concept of preamble. An MR ID concept for identifying MR in a cluster is proposed in the design of hierarchical preamble, in addition to the existing Cluster ID for identifying Cluster. The decision on either inter-cluster handover or intra-cluster handover is made by the signal quality measure of SMR(Signal MR to Adjacent MR signal power Ratio) and SCR(Serving Cluster to Adjacent Cluster signal power Ratio), provided by the preamble. The proposed handover procedure can simplify scanning procedure and skip/simplify network re-entry procedure (capability negotiation, authorization, registration), resulting in a significant reduction of handover overhead.
