The increased popularity of wireless networks has enabled the development of Location Based Service (LBS) techniques that rely on wireless signal strength. These techniques are being used extensively in military, healthcare, industrial and other environments in Wireless Sensor Networks (WSNs) and Mobile Ad hoc Networks (MANETs). In some networks, it is important to keep track of units/nodes that are mobile.

However, the overall accuracy of Wi-Fi triangulation in any network is affected by mobile nodes. Such effects are dependent on link failure, the relative speed of the node(s), signal strength, node density and the mobility pattern of the node(s). This article analyzes the effects of node mobility on Wi-Fi triangulation. Furthermore, recommendations are provided for developing methods to mitigate their negative effects on the accuracy of Wi-Fi triangulation. Our goal is to develop more accurate Wi-Fi triangulation techniques that are not affected by node mobility.
