Wireless Sensor Networks (WSNs) are composed of nodes that gather metrics like temperature, pollution or pressure from events generated by external entities. Localization in WSNs is paramount, given that the collected metrics must be related to the place of occurrence. This paper presents an alternative way towards localization in randomly deployed WSNs based on the composability of localization protocols. Results show a totally distributed localization procedure that achieves a higher number of located nodes than the conventional, individual execution of localization protocols while maintaining the same low levels of battery consumption.
