In order to analyze the performance of Wireless Local Area Networks (WLANs) effectively, it is important to identify those network settings that can cause the networks performance to go from good to poor. Low throughput, high packet loss rate, delayed round trip time (RTT), increased retransmissions, and increased collisions are the detrimental attributes(More)
A simple, specific, and sufficiently sensitive liquid chromatography-tandem mass spectrometry (negative-ion electrospray ionization) methodology to determine mevalonic acid (MVA) in human plasma is described, and its application to the analysis of rat plasma MVA levels after rosuvastatin administration is demonstrated. The method was validated over the(More)
Orthogonal frequency-division multiplexing (OFDM) modulation is a promising technique for achieving the high bit rates required for a wireless multimedia service. In this paper we present different channel estimation algorithms for OFDM mobile communication systems based on the use of pilot subcarriers. Specifically we present LS (Least Square), MMSE(More)
— Wireless Networks are most appealing in terms of deployment over a wide range of applications. The key areas are disaster management, industrial unit automation and battlefield surveillance. The paper presents a study over inter-operability of MANET (Mobile Ad-Hoc Network) protocols i.e DSDV, OLSR, ZRP, AODV over WSN (Wireless Sensor Network) [10]. The(More)
Mobile Networks are in need of what we call as an e-age. There have been numerous advancements in this field and soft computing has gained roots in this Mobile Ad-hoc Network domain. This documents studies the use of fuzzy logic over Ad Hoc On-Demand Distance vector Routing. The evaluation of the network using fuzzy logic over AODV has been conducted using(More)
This paper lays down a proposal of protocol named DREAM_OLSR. The protocol has been developed so as to effect current OLSR (RFC 3626) [4] protocol. The protocol establishes an optimized solution hence the name has been manipulated from Open Link State Routing to DREAM Optimized Link State Routing. DREAM specifies Distance Routing Effective Algorithm for(More)
In this paper we present an improved and robust channel estimation algorithm for OFDM mobile communication systems based on the use of pilot subcarriers.Specifically we present an iterative channel estimation technique to improve the performance of channel estimators.In iterative receiver structures, soft information becomes available after the decoding(More)
