A Multipath Approach for Improving Performance of Remote Desktop Transmission

Abstract—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 evaluated the performance of the proposed method using a network simulator and a real network environment. The experimental results revealed that the round trip time of a small data packet was shorter and the throughput of large amounts of data was higher than those with single network paths or existing multipath transmission algorithms
