In this article, a novel range-free localization algorithm is proposed based on the modified expected hop progress for heterogeneous wireless sensor networks where all nodes’ communication ranges are different. First, we construct the new cumulative distribution function expression of expected hop progress to reduce the computational complexity. Then, the elliptical distance correction method is used to improve the accuracy of the estimation distance and simultaneously decrease overhead. Finally, using the modified distance, the coordinate of the unknown node can be obtained by maximum likelihood estimation. Compared with other algorithms for heterogeneous wireless sensor network, the proposed algorithm is superior in the localization accuracy and efficiency when used in random and uniform placement of nodes.

Localization is an essential technology in the application of wireless sensor network. As a range-free localization algorithm, DV-Hop works well in dense and isotropic networks, but not much in irregular and sparse topologies, especially in the big curvature of shortest path case. In this paper, location information beyond the communication range was obtained by means of variable transmission power of enhanced nodes. Besides, three schemes was proposed to meet the need of different scenarios. Moreover, the simulation results validate that our method can improve position accuracy about 20% and ameliorate the performance of DV-Hop in irregular scenario.
