The sensor network supports data delivery from physical world to cyber space. The sensors get physical events then wireless network transfers sensor data to service server. We use sensor network technology to manage location information of an asset. In ubiquitous computing environment, user localization is basic context for intelligent service. A lot of research groups have made efforts to develop low cost localization technology. In this paper, we propose the design of multi-hop routing with asset monitoring system using wireless sensor network. It is implemented using ad hoc network technology which can be adapted to smart home and this system can monitor asset location and movement. We also test the performance of the routing engine with asset management system in a real ofice.
