An Energy-Efficient Data Dissemination in Wireless Sensor Network
Hoseung Lee, Ick-soo Lee, Kijun Han · 2009
In a sensor networks where a huge number of sensors are deployed, they select some particular nodes to work as active nodes and configures network topology with them to construct a long-lived network. Only the active nodes participate in message transmission through routing paths while the other nodes turn off their radios to save energy. Mobile sink mobility brings new challenges to sensor network. It suggests that information about mobile sink position be continuously propagated through the sensor field to keep all sensor nodes updated for the future data reports. In this paper, we describe a data forwarding scheme based on simple cross topology for wireless sensor network with mobile sinks. Simulation result shows that our scheme provides much greater energy efficiency than the conventional topology scheme.
