Executive Summary

Wireless Sensor Networks (WSNs) are the type of networks that are currently used in many applications. Some of these applications are critical and their information is very sensitive e.g. battle field and health care monitoring. Any transferred data has to be known from where it comes. In other words, most of the WSNs applications depend mainly on the location of each node in the network. In fact, the location may affect the decision to be made. The importance of localization is not only due to location identification but also it provides the base for routing, density control, tracking, and number many of other communication network aspects. Therefore, it is very important that each node reports its location accurately.
