Wiener Prediction Based Handoff Call Resource Management in Wireless Mobile Multimedia Networks
نویسندگان
چکیده
The objective of wireless mobile multimedia networks is to allocate required amount of resources to a mobile multimedia call. Reserving the resources 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 work presents an efficient handoff resource management method by considering the future resource demands of a wireless multimedia call. Here wiener prediction based resource estimation and reservation method is adopted to estimate the instantaneous resource demands of a mobile call. Cell segmentation technique is introduced and utilized to predict the resource demands more accurately in a real time manner. The simulation result shows the synergy of resource reservation using wiener prediction and cell segmentation have been decrease the call dropping probability of the handoff calls and enhance the micro and pico cellular system performance in real time manner..
