WLAN PERFORMANCE IMPROVEMENT BY HEADER COMPRESSION AND PACKET OVERHEARING REDUCTION
David Levy – Ivan Kotuliak – Peter Trúchly
For wireless systems, it is of vital importance to use the scarce radio resources in an efficient way. The main targets are to reduce the power consumption and increase the throughput of wireless devices. Using header compression both throughput can be increased and power can be saved. Using packet overhearing reduction power can be saved. This paper presents the achieved performance improvements when using these two methods. The simulation results are confirmed by analytical calculations. We show that we can achieve up to 35% power save when combining both methods and close to 0.1 additional normalized throughput.
