CLE2aR2: A cross-layer energy-efficient and reliable routing protocol for wireless ad hoc networks

The paper presents a cross-layer energy-efficient and reliable routing (named CLE²aR²) protocol to construct an energy efficient and reliable route and resist the variation of wireless channels for wireless ad hoc networks. CLE²aR²not only considers how to construct a route from the source to the destination, but also takes some important lower-layer factors, such as power strength, data transfer rate, and interference, into account to reflect the real situation of a wireless channel dynamically and instantly. Based on these factors, a reliable route can be constructed such that the retransmission cost can be reduced and the energy consumption can be saved. Simulation results also show that CLE²aR²can indeed construct an energy efficient and reliable route in comparison with the related work.
