Optimization of WLAN associations considering handover costs
In wireless local area network (WLAN) hotspots the coverage areas of access points (APs) often overlap considerably. Current state of the art optimization models find the optimal AP for each user station by balancing the load across the network. Recent studies have shown that in typical commercial WLAN hotspots the median connection duration is short. In such dynamic network settings the mentio...
متن کاملInterference Mitigation in Frequency-hopped Spread-spectrum Systems
| In this paper we explore the error probability of diierent coding schemes in a frequency-hopped spread-spectrum communication systems subject to partial-band interference and a system subject to Rayleigh fading. The interplay between block length of the code and channel memory is quantiied. We show that there is an optimal memory length that maximizes performance. At low signal-to-noise ratio...
متن کاملSpread spectrum interference suppression using adaptive time-frequency tilings
Interference suppression in spread spectrum communication systems is often essential for achieving maximum system performance. Existing interference suppression methods do not perform well for most types of nonstationary interference. We rst consider interference suppression schemes based on adaptive orthogonal time-frequency decompositions, such as wavelet packet and arbitrary dyadic time-freq...
متن کاملEffect of Interference of UMTS on WLAN
In this paper the effect of interference of UMTS is analysed on WLAN. The effect is analysed by varying the speed of UMTS nodes. To analyse this effect opnet modeler 14.5 is used. The interference is analysed in terms of Video traffic received, Voice traffic received and Load. Result shows that the better performance has been achieved in the absence of UMTS nodes as compare to their presence in...
متن کاملExperimental Evaluation of Interference Alignment for Broadband WLAN Systems
n this paper we present an experimental study on the performance of spatial Interference Alignment (IA) in indoor wireless local area network scenarios that use Orthogonal Frequency Division Multiplexing (OFDM) according to the physical-layer specifications of the IEEE 802.11a standard. Experiments have been carried out using a wireless network testbed capable of implementing a 3-user MIMO inte...
