When planning the structure of a backhaul mesh network for public access, it is common to introduce redundant nodes in the mesh network. These are called redundant, because they do not increase the network capacity under normal operation, due to the shortest-path metric of the routing protocol. Instead, their sole purpose is to increase the network reliability by providing failover links when a...

Broadband Video Streaming (BVS) with selective retransmission trades a reduced but acceptable video quality during IEEE 802.16e (WiMAX) hard handover (HHO) for improved end-toend latencies. BVS comes in two forms: selective and unselective retransmission when packet loss occurs. Both forms promise better video quality if an HHO occurs than UDP transport or traditional congestion-controlled stre...

Providing Internet connectivity to rural regions in developing countries is a challenging proposition. To effectively serve the needs of the rural poor, solutions need to be low-cost, in addition to being reliable and scalable. Mechanical backhaul networks are a low-cost solution to providing delay tolerant connectivity to such regions. In these networks, shared kiosk-based computers in village...

We present a recursive formula for estimating the packet loss rate in IP networks. Specifically, we consider a single link whose capacity is shared dynamically by elastic data flows, each characterized by some peak rate, and derive the formula from the steady-state distribution of the number and peak rates of ongoing flows. The result is particularly useful for dimensioning ISP backhaul network...

This contribution proposes that the scope of the MMR Task Group include 1) multiple relays rather than only a two-hop single relay path to the base station, 2) the option to study subscriber station relays in the path to the base station, and 3) the option to study relay for wireless backhaul. This contribution also proposes definitions for performance metrics to be used in comparing mobile mul...

The recently proposed NR-ready integrated access and backhaul (IAB) architecture promises to bring a cost-efficient deployment solution for both coverage extension capacity boosting in the emerging 5G/5G+ systems. While its impact on was thoroughly addressed literature, effect of advanced functionalities such as multihop, multi-connectivity, multi-beam operations throughput remained unclear. We...

In drone assisted mobile networks, drones mounted small cell base stations (DBSs) are responsively and flexibly deployed over any Places of Interest (PoI), such as sporadic hotspots disaster-struck areas, where the existing network infrastructure is unable to provide wireless coverage. Here, a DBS relay node traffic between nearby macro station (MBS) users. addition, Free-space optics (FSO) app...
