MEMO: An Applied Wireless Mesh Network with Client Support and Mobility Management

In this paper, we design and implement an applied wireless mesh network named MEMO with transparent client access support and mobile node mobility management. Unlike traditional design, our proposed solution is based on MAC layer triggered mechanism and special routing scheme called AODV_MEMO which combines routing and mobility management into a single solution. The advantages of AODV-MEMO solution include: (1) no modification is required on mobile nodes; (2) mobility management is accomplished in distributed way, no central location server is needed; (3) cross- layer interaction between MAC and Routing Layer effectively reduces the handover time of mobile nodes roaming. In addition, an effective gateway function has been implemented based on the AODV-MEMO routing. Real test-bed experiment proves our design is feasible and efficient.
