A wireless personal area network (WPAN), which virtually, a synonym since almost any personal area network would need to function wirelessly. Conceptually, the difference between a PAN and a wireless LAN is that the former tends to be centered around one person while the latter is a local area network (LAN) that is connected without wires and serving multiple users. In another usage, a personal area network (PAN) is a technology that could enable wearable computer devices to communicate with other nearby computers and exchange digital information using the electrical conductivity of the human body as a data network. Here we investigate a PAN encounter problems of ping-pong effect and network instability when two or more PAN'S enter the same boundaries to establish a larger PAN in an ad-hoc fashion i-e piconet and scatternat. To overcome these we propose a novel algorithm to select the Master Device in a Personal Area Network, communicating with other PANs in an ad-hoc manner, by considering Reach-ability & Stability as the two prime selection criteria along with other factors to solve the problems of ping pong effect and the WPAN instability due to the handovers between devices by using OPNET simulator.
