Remote desktop systems enable business users to access critical data located in the office from outside it with a mobile thin client or any other portable ubiquitous devices without having to worry about data leakage. However, high latency and low bandwidth in wireless-network environments may degrade the performance of remote desktop clients, such as causing slow responses to keyboard/mouse input and low speed in playing animated presentations. We therefore propose a method of transmitting data to improve the way business applications are perceived in wireless thin clients. It utilizes multiple wireless-network paths to achieve short latency in transmitting input signals and receiving responses as well as increases the throughput of large desktop images. We present the results of implementation in a laboratory network environment that validate the superiority of the proposed method.
