    Abstract: Following the development of Information technologies, wireless sensor networks (WSNs) are widely used in many areas in recently years. How to collect information efficiently and deliver to base station reliably is one of important issue among the hot topics in WSNs. Most of the previous studies used the Geographic routing to resolve this problem. Sensors have to know not only their location information, but also one hop neighbor and destination location information. Generally, the Global Positioning System (GPS) provides location and time information, but it will increase the cost, power consumption, and reduce the lifetime of wireless sensor network. In this paper, we propose a Virtual Coordinate System (VCS) start from sink to replace GPS. With the VCS, WSNs can find the four extreme nodes in the scene boundary as virtual anchor nodes. Then, a shortest path between virtual anchor nodes and sink for transfer data in the random distribution wireless sensor network is created. In this approach, establish a low-power, extend the network lifetime, efficient and fault-tolerant routing mechanism.
