Why the Accuracy of the Received Signal Strengths as a Positioning Technique Was Not Accurate?
There is a great need for having reliable and accurate positioning technique for many wireless network technologies such as the Wireless Ad Hoc Networks, Wireless Sensor Networks, Vehicular Ad Hoc Networks, and Wireless Local Area Networks. In addition, the Mobile Computing which still in the development phase requires good localization system for the mobile nodes. The system must allow each node to know precisely its current position or location in real time. Despite the many works that exist in the literature in this area, all of the proposals have some limitations.
