Special Issue on "Wireless Multi-Hop Networking for Infrastructure Access"
Multi-hop wireless networks in all their different forms continue to receive much attention. Multi-hop techniques are viewed as an important component of next generation radio access networks, in which end user terminals may be multiple wireless hops from the wired infrastructure. Most of these multi-hop radio access deployments are characterized by intermediate nodes with limited mobility which differentiates these problems from those arising in an ad hoc domain. However, realizing these benefits is highly non-trivial, requiring an excellent understanding of all aspects of a radio system. There are a number of interesting initiatives in this space. The IEEE 802.16j standard is in the very final stages of ratification and new standards are considering how multi-hop capabilities can be incorporated, e.g., LTE-A and 802.16 m.
