Abstract

Next generation wireless communications system will be required tosupport the seamless delivery of voice, video and data with high quality.Delivering hard Quality of Service (QOS)assurances in the wireless domain is complex due to large-scale mobilityrequirements, limited radio resources and fluctuating network conditions. Toaddress this challenge we are developing mobiware, a QOS-awaremiddleware platform that contains the complexity of supporting multimediaapplications operating over wireless and mobile networks. Mobiware is ahighly programmable software platform based on the latest distributedsystems technology (viz. CORBA and Java). It is designed to operate betweenthe application and radio-link layers of next generation wireless and mobilesystems. Mobiware provides value-added QOS support by allowing mobilemultimedia applications to operate transparently during handoff and periodsof persistent QOS fluctuation.
