REACTIVE GRASP WITH PATH RELINKING FOR BROADCAST SCHEDULINGCommander, Clayton W.; Butenko, Sergiy I.; Pardalos, Panos M.; Oliveira, Carlos A.S.; Eglin Air Force Base; Texas A&M University; University of Florida (International Foundation for Telemetering, 2004-10)The Broadcast Scheduling Problem (BSP) is a well known NP-complete problem that arises in the study of wireless networks. In the BSP, a finite set of stations are to be scheduled in a time division multiple access (TDMA) frame. The objective is a collision free transmission schedule with the minimum number of TDMA slots and maximal slot utilization. Such a schedule will minimize the total system delay. We present variations of a Greedy Randomized Adaptive Search Procedure (GRASP) for the BSP. Path-relinking, a post-optimization strategy is applied. Also, a reactivity method is used to balance GRASP parameters. Numerical results of our research are reported and compared with other heuristics from the literature.
