New Technique of Wireless Sensor Networks Localization based on Energy Consumption

Localization has newly received research interest due to the success of the emerging wireless sensor network (WSN) technology. This interest is expected to grow further with the proliferation of wireless sensor network applications such as medicine, military, transport... In this context routing, protocols and technologies of communication on those wireless area are enormously applied to sensor networks in order to improve the quality of service and communication. Related to this work, we present on this article a briefly some techniques of localization techniques on wireless sensor networks and propose a localization method based on the angle of transmission of directional antenna and the energy consumption of the node when sending a data. Then we compare the mentioned method to TDOA technique (Time Differential Of Arrival) applied on the context of mobility characterizing the transport domain and compare their performance when localizing sensors in this kind of applications.
