The proposed technique is based on Simulated Annealing algorithm (SA) and is called MSMR-M. The performance study in this work is based on simulation. We compare other node-placement techniques found in the literature with the optimal node-placement solutions obtained from our optimization. The results show that using the optimal node-placement obtained by our proposed technique can improve the positioning error distances up to 20% better than those of the other techniques. The proposed technique can provide an average error distance within 1.42 meters. }, journal = {International Journal of Electronics and Communication Engineering}, volume = {8}, number = {7}, year = {2014}, pages = {1191 - 1195}, ee = {https://publications.waset.org/pdf/9998851}, url = {https://publications.waset.org/vol/91}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 91, 2014}, }
