Scenarios enabled

OneFIT enables efficient business and service offerings in important scenarios (Figure 1). The chosen scenarios are:

  • Opportunistic coverage extension;
  • Opportunistic capacity extension;
  • Infrastructure supported opportunistic ad-hoc networking;
  • Opportunistic traffic aggregation in the radio access network;
  • Opportunistic resource aggregation in the backhaul network

Figure 1. OneFIT applied in various scenarios: (a) Opportunistic coverage extension; (b) Opportunistic capacity extension; (c) Infrastructure supported opportunistic ad-hoc networking; (d) Opportunistic traffic aggregation in the radio access network; (e) Opportunistic resource aggregation in the backhaul network.



Scenario 1 "Opportunistic coverage extension" describes a situation in which a device cannot connect to the network operator's infrastructure, due to lack of coverage or a mismatch in the radio access technologies. The proposed solution includes one or more additional connected users that, by creating an opportunistic network, establish a link between the initial device and the infrastructure, and act as a data relay for this link.

Scenario 2 "Opportunistic capacity extension" depicts a situation in which a device cannot access the operator's infrastructure due to the congestion of the available resources at the serving access node. The proposed solution proposes the redirection of the access route through an opportunistic network that avoids the congested network segment.

Scenario 3 "Infrastructure supported opportunistic ad-hoc networking" shows the creation of an infrastructure-less opportunistic network between two or more devices for the local exchange of information (e.g. peer-to-peer communications, home networking, location-based service providing, etc.). The infrastructure governs the ON creation and benefits from the local traffic offloading, as well as on new opportunities for service providing.

Scenario 4 "Opportunistic traffic aggregation in the radio access network" describes the usage of a local opportunistic network among several devices, in order to share a reduced number of infrastructure links towards a remote service-providing server or database. This situation allows some degree of traffic aggregation and caching that is useful to improve the overall network performance.

Scenario 5 "Opportunistic resource aggregation in the backhaul network" depicts how opportunistic networks can be used to aggregate both backhaul bandwidth and processing/storage resources on access nodes. In this case, the ON is created over access points rather than user terminals, thus offering a new focus on system performance improvement.
