Development and validation of a localization framework for wireless sensor networks (original) (raw)

Wireless sensor networks localization is an important area that is required in many wireless sensor network applications. It is rather complex or even unfeasible; to model analytically WSN localization and it usually leads to oversimplified analysis with limited confidence. Besides, deploying test-beds supposes a huge effort. Therefore, simulation is essential to study WSN localization. However, it requires a suitable model based on solid assumptions and an appropriate framework to ease implementation. Most of WSNs simulators fail to support all the following criteria: easy, extendable and scalable, so that we design and implement an integrated framework used for localization in WSNs and available for the analysis of different types of localization schemes (Range-free, Range-based and Hybrid localization algorithms). The obtained framework is simple and easy to be used to demonstrate the performance evaluation and comparison of different types of localization schemes. It can also be extended to include many localization algorithms by future researchers.
