In the present study, two new methods for sensor localization have been proposed, which are indeed a compromise between rangebased and range-free techniques. In the proposed methods, the sensors make use of omnidirectional antenna for transmission of their usual information, and information processing is performed only through some sensors called landmark. The lack of need for complex processing, reduction in the energy consumption, and high precision in locating the geographical coordinates are among the most important features of the suggested protocols. Simulation results show that the proposed methods are highly efficient while reducing system’s complexity.
