Sensor networks have many applications, a typical setting is in nature environment monitoring, such
as forest fire, tsunami, and earthquake. In order to be easily deployed in this environment, sensor device is design to have small form factor, and as lightweight as possible, thus, its battery capacity is limited. The issue of battery capacity is more important when applied in tracking moving objects, and when real time response of the system is critical where the routing algorithm do not need to perform data aggregation. This paper proposed a routing algorithm for tracking objects and perform emergency reporting when a situation occurred and at the same time reducing total energy consumption and thus prolonging the system lifetime. Our algorithm is called sensor on demand betweenness vector(SOBV). This algorithm is a multipath routing algorithm based on the characteristics of network topology.
