Abstract

This paper presents an innovative extension to routing protocols using a back-tracing technique to improve performance of handovers in wireless mesh networks. The main purpose of this extension is to minimize disconnection time and packets losses when mobility occurs. The proposed scheme requires some minor changes to the original proactive ad-hoc routing protocol, but does not impose any modification to the current IEE 802.11 MAC protocol. Some additional changes are also required to the handover signalling, in order to better optimize the process. The back-tracing mechanism is also able to reach route convergence to a minimum route length maintaining the throughput of data packets. The results of the proposed extension show that it is able to maintain the network throughput in wireless mesh networks during mobility, minimizing the packet losses.
