A study of profiled handoff for Diffserv-based mobile nodes
There is a growing interest in providing Internet services to the mobile nodes. When mobile nodes travel from one router's service area to another, the time-sensitive applications may see degradation in service. We investigate into the effects of handoff on service quality of mobile nodes. Several experiments are conducted using various packet metering and marking schemes with or without transferring profiles to the new router. Results indicate the relative instability period following handoff, loss of packets and delay encountered by packets in profiled or un-profiled handoffs, leading to determining suitable mix of metering and marking schemes with or without context transfer.
