Wireless download agent for high-capacity wireless LAN based ubiquitous services

We propose a wireless download agent which effectively controls the point at which a download starts for providing a comfortable mobile computing environment. A user can get the desired data with the wireless download agent while walking through a service area without stopping. We conducted simulations to evaluate its performance in terms of throughput, download period, and probability of successful download. Our results show that the proposed scheme very well suits the wireless download agent in high-speed wireless access systems with many users. Furthermore, we describe the use of the proposed scheme considering the randomness of the walking directions of users.
