The Impact of Random Waypoint Mobility on Infrastructure Wireless Networks

In this paper we report on the impact of the Random Waypoint model on infrastructure wireless networks that use multi-rate schemes. The Waypoint model causes a higher concentration of nodes near the centre of the mobility area. Consequently, we show that a wireless network could appear to achieve higher capacity, and that base stations near the centre of the mobility area will experience higher frequencies of transmission rate change. These aberrations could affect simulation results that should be interpreted with care.
