An Opportunistic Scheduling Scheme with Minimum Data-Rate Guarantees for OFDMA
Abstract—We tackle the problem of providing minimum datarate guarantees for different classes-of-service in an OFDMAbased network, while obtaining a high system throughput. Our a...

Randomized k-Coverage Algorithms For Dense Sensor Networks
— We propose new algorithms to achieve k-coverage in dense sensor networks. In such networks, covering sensor locations approximates covering the whole area. However, it has been...

Effectiveness Bounds for Non-Exhaustive Schema Matching Systems
Semantic validation of the effectiveness of a schema matching system is traditionally performed by comparing system-generated mappings with those of human evaluators. The human ef...
