Cell segmentation based handoff call resource management in wireless cellular mobile networks

The main aim of future wireless multimedia networks is to provide sufficient amount of resource to a multimedia call. Reserving required amount of resource in advance to a future new and handoff call is better than rejecting a call at neck of the moment due to insufficient resource at a particular time. This paper presents an efficient handoff resource management strategy by considering the future resource demands of a wireless multimedia call. Here a novel wiener based resource estimation and reservation method is adopted to estimate the instantaneous resource demands of a mobile user. Cell segmentation technique is introduced and utilized to predict the resource demands more accurately in a real time manner. The performance result shows this synergy of resource reservation using pilot sensing and cell segmentation have been decrease the call dropping probability of the handoff calls and increases the micro and pico cellular system performance in real time environments.
