چکیده
In wireless sensor network routing protocol design and energy savings optimization is important because most of times nodes are in moving condition and deployed in remote area. This work focuses on minimizing energy consumption and maximizing network lifetime for data relay in one-dimensional queue network. An Energy Saving via Opportunistic Routing (ENS_OR) algorithm is designed to ensure minimum power cost during data relay and protect the nodes with relatively low residual energy. ENS_OR adopts a new concept called energy equivalent node (EEN), which selecting relay nodes based on opportunistic routing theory, to derive the optimal transmission distance for energy saving and maximizing the lifetime of whole network.
