Performance evaluation of different optimization techniques for coverage and connectivity control in backbone based wireless networks

摘要

In this paper, performance evaluation of Newton-Raphson and ConjugateGradient method has been studied in comparison to Steepest Decent method forcoverage and connectivity control in backbone based wireless networks. In orderto design such wireless networks, the main challenge is to ensure networkrequirements such as network coverage and connectivity. To optimize coverageand connectivity, backbone nodes will be repositioned by the use of mobilitycontrol based on above mentioned methods. Thus the network get self organizedwhich autonomously achieve energy minimizing configuration. Furthermore bysimulation using MATLAB R2010a, methods are compared on the basis of optimizedcost, number of iterations and elapsed time i.e. total time taken to executethe algorithm.
