Performance of Disparate-Bandwidth DS-SS Systems in Spectral Overlay Ad Hoc Networks

Abstract Details

2009, Master of Science (MS), Ohio University, Electrical Engineering (Engineering and Technology).
In this thesis we investigate the performance of direct sequence spread spectrum(DS-SS) overlay ad hoc networks by performing computer simulations and numerical evaluations based upon mathematical analysis. Two such DS-SS systems, with different bandwidths, are studied. We investigate performance statistics for a terrestrial network model in a limited two-dimensional area, in which user (node) locations are random, and statistics are gathered over numerous realizations of these random node locations. For all users in both systems we collect statistics on performance in terms of signal-to-noiseplus-interference ratio (SNIR) and bit error probabilities, to illustrate aggregate behavior attainable in such systems. We first illustrate our technique for a specified reference system with a given set of parameters, then we vary several of these parameters to assess the effects on performance. Parameters we vary include transmit power, data rates,processing gain, path loss exponent and shadowing standard deviation. We demonstrate that overlay of different-bandwidth DS-SS systems in an ad hoc network can be practical by specifying appropriate system design parameters.
