In wireless sensor networks, multi-hop communications is a must given the nodes’ limited communication coverage compared with the size of the area of interest. In this case, intermediate nodes must relay packets so they can travel from source to sink. This is the function of the network layer: routing packets from the source node to the destination, normally the sink node, through the wireless multi-hop network. This function is particularly challenging in WSNs considering the computational and energy constraints of the nodes and the network-wide function that it needs to accomplish. This chapter presents the most important routing approaches for WSNs considering small and large-scale networks.
