Improved recursive DV-Hop localization algorithm for average hop distance optimization

Aiming at the problem of DV-HOP algorithm with error and energy exhaustion, average hop distance is used for optimization, an improved recursion method to solve it. The first squares anchor nodes, proposes a forgetting factor optimize between secondly uses recursive operations replace nodes insufficient energy, so that localization process unknown can continue. Experimental results show compared DV-Hop algorithms in related literature, reduce certain extent improve accuracy nodes.
