Wireless Multi-hop Networks: Classification, Paradigms and Constraints

Over the last years research on wireless multi-hop networks has gained momentum. Wireless multi-hop networks come in many different flavors, all having their own characteristics, requirements and specific constraints. While ambiguous definitions of multi-hop networks are used in the literature, we believe that different types of multi-hop networks should be differentiated more clearly. With this article, we attempt to present a strict classification and concise naming of the different wireless multi-hop networks. We will distinguish between cellular multihop, pure ad hoc, ad hoc access, and mesh networks. Furthermore, we will present typical characteristics and constraints for each multi-hop network class, and highlight current research topics. With this contribution, we intend to help shape and sharpen the view on multi-hop networks.
