Overview Bluetooth is a wireless ad-hoc network concept primarily intended to eliminate the cables between portable and/or fixed electronic devices. In this paper, a non-real-time communication service in Bluetooth is considered. Depending on its QoS (Quality-of- Service) requirements, the non-real-time traffic is divided in two classes - class1: delay-tolerant traffic like email and paging; and class2: delay-sensitive traffic like ftp and remote log-in. class2 is given priority over class1. Two new scheduling policies are proposed with an attempt to provide high performance service in terms of delay and throughput to higher priority class while fairly distributing the link resources to lower priority class.
