Wireless Sensor Networks (WSNs) have gained worldwide attentions in recent years. Since WSNs can be conveniently deployed to monitor a given field of interest, they have been considered as a great long-term economic potential for military, environmental, and scientific applications etc. One of the most active areas of research in WSNs is the coverage which is one of the most essential functions to guarantee quality of service (QoS) in WSNs. In this work, the coverage control problems in heterogeneous WSNs have been analyzed. The Delaunay Triangulation and modified ideal distance coefficient have been employed into traditional virtual force algorithm (which often used in homogeneous WSNs) to improve the QoS of the deployment. In order to validate the performance of the proposed algorithms, numerical simulations for heterogeneous WSNs cases have been considered in this work. The simulation results verify the effectiveness of this proposed algorithm.
