Abstract
Wireless sensor networks provide an opportunity of innovations while also brings unique challenges. Collaborations between sensor nodes are generally required for complicated applications. As a key component for node collaboration, robust routing protocols that are able to effectively communicate among multiple nodes become necessary. In wireless sensor networks, these protocols are energy efficient and provide low latency. In this paper, we develop optimal distance geographic routing (ODGR), an application-independent protocol using power control in the transmission scheme and the available geographic information to dynamically explore the optimal routing path in order to reduce the total transmission energy and routing latency. ODGR is built on the optimal distance theory derived exclusively from the fundamental transmission energy model. Detail procedures of ODGR are presented for practical implementations. Case study of a two-dimensional mesh network shows that ODGR is able to reduce total transmission energy by 66.41% and 43.89%, and average latency by 76.45% and 26.27% respectively compared to traditional MTE and cluster algorithms, thus ODGR can improve the system-life and the performance of wireless sensor networks.
