Abstract:
Future network architectures, such as Next Generation Network (NGN) and Vehicular Communication Network (VCN), will provide large scale mobile Internet access supported with multiple and small cells of wireless communication. Therefore, the access to the Internet services are prone to very frequent disconnections when the mobile node migrates across the cells. This paper deals with this concern and discusses issues involved on the modelling of mobility-aware applications. An abstract model is described by means of two Finite State Machines (FSM) designed for both mobile nodes, client and server. The FSMs are meant to networked applications to preserve their integrity in the event of frequent connection disruptions in Single Jumps (client side mobility) and Double Jumps (both client and server sides mobility). The FSMs for mobility-aware applications were evaluated using a handover delay mathematical model. With handover latencies from 230 ms in single jumps and from 450 ms in double jumps, simulation results show that the proposed strategies are capable of providing automatic Transmission Control Protocol (TCP) connection re-establishment with smooth impact when increasing the frame error rate and the data lost in handovers.
