Localization procedure for randomly deployed WSNs based on the composability of position estimation protocols

Wireless Sensor Networks (WSNs) are composed of nodes that gather metrics such as 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 work presents an alternative way towards localization in randomly deployed WSNs based on the combination of individual position estimation protocols (composability). Our solution provides a flexible approach towards the localization problem in WSNs, which by means of composability it is able to locate more nodes than exclusively using a single localization protocol, while maintaining the same low levels of battery consumption.
