Abstract—We consider variations of a problem in which data must be delivered to mobile clients en route, as they travel toward their destinations. The data can only be delivered to the mobile clients as they pass within range of wireless base stations. Example scenarios include the delivery of building maps to firefighters responding to multiple alarms. We cast this scenario as a parallel-machine scheduling problem with the little-studied property that jobs may have different release times and deadlines when assigned to different machines. We ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

Abstract
In this paper, we examine the problem of assigningcalls in a cellular mobile network to channels in the frequencydomain. Such assignments must be made so that interferencebetween calls is minimized, while demands for channels aresatisfied. A new nonlinear integer programming representationof the static channel assignment (SCA) problem is formulated.We then propose two different neural networks for solving thisproblem. The first is an improved Hopfield neural network whichresolves the issues of infeasibility and poor solution q ....etc
