uSD: An SD-Based Mobile Gateway to Wireless Sensor Network

This paper presents an SD-based mobile gateway to wireless sensor network (WSN), named uSD, which aims at helping users with mobile terminals to access WSN conveniently and efficiently. The prefix "u" of uSD illustrates its most significant characteristic: universality, which means uSD is platform independent and compatible with heterogeneous platforms, truly plug-and-play. In this paper, we first discuss some related works. Then the design and implementation of uSD are amply illustrated, especially about the uSD's superiority over SDIO-based method. Through simulation, one important parameter is obtained. At last, a practical work is shown. The result of this work not only validates uSD's feasibility, but also well demonstrates its platform independence.
