TopIn the literature, several cross-layer approaches have been proposed in order to improve the performance of transmissions in wireless sensor networks. In this work, the authors are interested in approaches dealing with the data link layer with its MAC protocol and the network layer with its routing protocol.
According to (Fedor, Collier, & Sreenan, 2011) there are two types of cross-layering between the network layer and the data link layer. In the first type, the functionalities of the MAC protocol and the routing protocol are combined in a single approach. SIF (Chen, Deng & Varshney, 2005) is one of these approaches, it combines a routing approach with a collision-based MAC approach. IDeg-Routing&MAC (Louail & Felea, 2016a) also combines a geographic routing approach with a collision-free MAC approach. In the second type, one approach takes advantage of the information coming from the other approach. The MAC approach uses the information of the routing approach like in CoLaNet (Chou & Chuang, 2005) or IDeg-ReLO (Louail & Felea, 2016b). Also, the routing approach uses the information of the MAC approach as in ORW (Landsiedel, Ghadimi, Duquennoy & Johansson, 2002) and MAR-WSN (Louail, Felea, Bernard & Guyennet, 2015).
