Scheduling? • Literal definition (Wikipedia) • Scheduling is the process of deciding how to commit resources between a variety of possible tasks. Time can be specified or floating as part of a sequence of events. • Link scheduling: Formal form in wireless networks • There are M possible links for N nodes in the same interference range, decide a link Mi to be active • For MOVi, Link scheduling • Objective: Maximize Throughput Rate (Minimize QoS Deg.) given by Conflicts of interest • For MOVi, Segment scheduling • How to decide Conflicts of interest? • Objective: Balance QoS deg. and rarity given by cache map of each node • Is it “Chicken or the egg Problem”? • Conflicts of interest changes possible links • The out put of a link scheduling changes the conflicts of interest 1 3 2 4 N 5 6
