Polar interval-based localization in mobile sensor networks

International audienceThe problem of localization in uncontrolled mobility sensor networks (MSN) is considered. Based on connectivity measurements the problem is solved using polar intervals. Computation is performed, in several polar coordinate systems (PCSs), using both polar coordinates and interval analysis. Position estimates are thus partial rings enclosing the exact solution of the problem. Simulation results corroborate the efficiency of the proposed method compared with existing methods, especially with those handling single coordinate systems
