Wireless Random Access Performance Improvement via Enhancement of Contention and Floor Reservation Mechanisms Mohammad Hossein Bateni mh bateni@ec iut ac ir November 27 2018 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree Doctor of Philosophy PhD Language FarsiSupervisors S Jamaloddin Golestani Assist Prof golestani@ee sharif edu Ali Mohamad Doodthoseini Assoc Prof alimdh@cc iut ac ir AbstractThe proficiency of the wireless random access scheme drastically contributes to the overall performance ofmany modern wireless networks which target the flexible and reliable exchange of bulks of information betweennumerous nodes The new requirements of such networks thus necessitate the design of novel approaches torevolutionize our view to the wireless random access problem An interesting idea in this field is the cross layerdesign approach which incorporates the inherent capabilities of the radio interface to help control the accessof nodes to the shared wireless medium more effectively The novel scheme proposed in this dissertation im proves the random access efficiency via optimized floor reservation mechanism and an agile criteria of signalingtogether with powerful contention resolution strategies Also presented is a unified analytic framework for per formance evaluation of a wide class of wireless random access schemes which explicitly distinguishes betweenthe temporal and spatial aspects of the random access performance and enables the quantitative comparison ofdifferent schemes The performance of the proposed scheme together with the suggested contention resolutionstrategies is evaluated and compared with that of IEEE 802 11 DCF as an accepted baseline through extensiveanalytic discussion and appropriate simulations confirming the proficiency of the proposed scheme Keywords1 Wireless Random Access 2 Carrier Sense Multiple Access with Collision Avoidance CSMA CA 3 Re quest Pulse RP 4 Throughput 5 Contention Resolution 6 Temporal Spatial Efficiency
