Atlantis Press Paper Details: Dynamic Handoff Ordering Adjustment for Multimedia Cellular Network

In multimedia cellular network, a Mobile Host (MH) requests multimedia services and may experience handoffs to several cells. When the target cell cannot provide adequate bandwidth for a service, instead of directly dropping a request, the MH is put into the handoff queue and hopefully the request bandwidth can be satisfied by later released bandwidth. Obviously, it is important to properly assign priorities for queued handoffing MHs based on their inborn dynamics to avoid unnecessary dropping. In this paper, we present a dynamic handoff priority adjustment (DHPA) scheme which applies handoff queuing scheme to order handoff requests and adjust handoff priority based on receiving signal strength, service class, and mobility of MHs. The goal of DHPA is to reduce call dropping probability to maintain QoS for users and also increase bandwidth utilization of multimedia wireless network.

abstract:		In multimedia cellular network, a Mobile Host (MH) requests multimedia services and may experience handoffs to several cells. When the target cell cannot provide adequate bandwidth for a service, instead of directly dropping a request, the MH is put into the handoff queue and hopefully the request bandwidth can be satisfied by later released bandwidth. Obviously, it is important to properly assign priorities for queued handoffing MHs based on their inborn dynamics to avoid unnecessary dropping. In this paper, we present a dynamic handoff priority adjustment (DHPA) scheme which applies handoff queuing scheme to order handoff requests and adjust handoff priority based on receiving signal strength, service class, and mobility of MHs. The goal of DHPA is to reduce call dropping probability to maintain QoS for users and also increase bandwidth utilization of multimedia wireless network.
