Abstract
Improvement in the Priority Handoff Scheme for Multi-Service Wireless Mobile Networks
Highlights
With the rapid development of mobile communication technology, support for multimedia applications in an increasing number of users has forced service providers to employ cells of smaller size so that availability of adequate capacity could be ascertained
They (Zhihua, 2008) have recently proposed a strategy to dynamically reserve guard channel for handoff calls. This increased the bandwidth utilization, but did not consider the different priorities between the various data services. They (Huang and Chan, 2004) proposed a movable boundary and guard channel strategy, they consider two priorities that real time service has a higher priority than the non-real-time service and the handoff call has a higher priority than a new call
The arrival rate of new calls λo = (1.34-8.04) /min, the arrival rate of handoff calls λh = (1.66-5.0) /min
Summary
With the rapid development of mobile communication technology, support for multimedia applications in an increasing number of users has forced service providers to employ cells of smaller size so that availability of adequate capacity could be ascertained. They (Huang and Chan, 2004) proposed a movable boundary and guard channel strategy, they consider two priorities that real time service has a higher priority than the non-real-time service and the handoff call has a higher priority than a new call. The performance of new calls has been reduced and this strategy did not consider the different priorities between the various data services.
