In order to evaluate the behavior and performance of protocols for wireless networks, simulations are a good compromise between cost and complexity, on the one hand, and accuracy of the results, on the other hand. Since there are many simulators for wireless networks, it is often difficult to decide which simulator to choose. To help shed light on this(More)
The IEEE 802.21 standard facilitates media independent handovers by providing higher layer mobility management functions with common service primitives for all technologies, thus hiding the technology specifics of the lower layers. Right after the base specification was published, several voices rose up in the working group advocating to broaden the scope(More)
For the evaluation of wireless network protocols, simulation has established itself as a good compromise between cost and complexity, on the one hand, and accuracy of results, on the other hand. Most established network simulators, however, were originally developed for wired networks and only later extended to the wireless domain. Some simulators like(More)
— This work presents Xhaul: the 5G Integrated Fron-thaul/Backhaul. Xhaul aims at developing an adaptive, sharable, cost-efficient 5G transport network solution integrating the fronthaul and backhaul segments of the network. This transport network will flexibly interconnect distributed 5G radio access and core network functions, hosted on in-network cloud(More)
The task of a MAC protocol is to manage the access to the (wireless) medium so that it can be shared by multiple nodes. TDMA MACs achieve this by providing non-overlapping access schedules. Typically, such schedules are dictated by a set of master nodes or negotiated between the nodes in a preliminary phase by exchanging messages. This has to be(More)
—In this paper, we present a novel multipath structure called rope-ladder which combines the advantages of path, node and link protection schemes. We also propose a position-based multipath routing protocol in order to efficiently construct rope-ladders in wireless networks. By design, the paths which are constructed by our protocol are closely together(More)
