  In this paper, performance evaluation of Newton-Raphson and Conjugate
Gradient method has been studied in comparison to Steepest Decent method for
coverage and connectivity control in backbone based wireless networks. In order
to design such wireless networks, the main challenge is to ensure network
requirements such as network coverage and connectivity. To optimize coverage
and connectivity, backbone nodes will be repositioned by the use of mobility
control based on above mentioned methods. Thus the network get self organized
which autonomously achieve energy minimizing configuration. Furthermore by
simulation using MATLAB R2010a, methods are compared on the basis of optimized
cost, number of iterations and elapsed time i.e. total time taken to execute
the algorithm.
