Localization For Ad Hoc Networks Using ZigBee

A new technology development nowadays in wireless sensor network has already achieved to its potential to become complementary to every person in this world. This report shall be present about the progress that have been made and the future works that will be done to finish this project. An ad hoc network is a wireless network which is consists of decentralized structure comprised of nodes. Therefore, there will be no central administration and each node can participate freely in transmission. In order to apply the positioning system in ad hoc network, localization is one of the most essential technologies to obtain accurate location information. There are many methods in localization technologies and one of them is by using the signal strength of each node. GPS (Global Positioning System) is one of the system that using the localization technologies which involved satellites. However, buying a GPS module or device would be expensive and GPS module cannot be used for indoor positioning. Thus, this project’s aim is to design a cheap and low cost of localization technique in ad hoc network using ZigBee mesh network. Trilateration, which is one of the localization techniques, will be used based on signal strength measurement of each node.
