measurements by the APN. The frequency of observation increases
as APN senses the severity of the accumulation. Depending on the
density and stretch of the accumulation, each remote site is rarified
or densified with resources forming the intricate pattern shown in
Figure 6. The pattern restructures with the movement of the groups.
Eventually, the network reverts to the typical situation when the
group disperses or disintegrates. Using sophisticated algorithms
[5], the SCIDAS can respond to regular wobbles in the network.

MULTITECHNOLOGY ENVIRONMENT
Managing the multitechnologies in the same geographical area is
even more efficient with SCIDAS architecture. This is due to that
fact that SCIDAS disseminates the BS resource in the geographic
scope and has nothing to do with the type of technology in use.
The only upgrades required are the BSs at the hub and compatible
antennas at the remote ends. This not only saves a lot on the intermediate infrastructure but also on the time of deployment. Hence,
as the accumulation is typical for any technology, the SCIDAS
can suitably tackle the multitechnology environment by managing
the resource allocations of all the BSs that are situated in the hub.
In Figures 5 and 6, we can see that SCIDAS uses its distributed
antennas to sense the accumulations and then allocates the resources
intelligently to create tunnels for groups to move out of area of interest or reconfigure resources for static users. The change in the user
densities in a propagation environment changes its properties which
can be sensed by the antennas of the SCIDAS that can be analyzed by
NIU to identify the locations of user wobbles. NIU can then decide
to allocate resources iteratively to cater to excess users. This may

not completely solve the issue; however, the concept provides many
opportunities to investigate PTC2 problems and improve the concept.

SIGNIFICANCE OF CONASENSE
As we know, CONASENSE stands for the integration of Communication, Navigation, Sensing, and Services. The SCIDAS
concept finds itself very much suited to the CONASENSE arena.
As discussed earlier, and shown in Figure 5, SCIDAS uses variations in propagation properties of the surrounding environment
to probe (sense) the network. Figure 6 shows that each and every
site of SCIDAS can be exclusively controlled by NIU to create a rhythmic response, which is in synchronization with the
users' behaviors across the network. Depending on the type of
services that users are accessing under each site, the throughputs
across the SCIDAS network can be adjusted by the network intelligence.
The SCIDAS architecture is conceptualized to have a unique
property of disseminating SCIN resources in the network area.
This means that SCIDAS can easily accommodate upgrades and
network expansions. The newer technologies may require less or
negligible revamping than those networks that do not have SCIDAS arrangements. Due to the simplification of architecture, the
SCIDAS may accommodate other kinds of services that may not
be possible with other networks. The unique concept can be combined with other platforms, as discussed in [6], which uses drones
to provide cellular networks in difficult cases when usual networks
fail to integrate. Contemplating on this property, we can also combine navigation services with SCIDAS as future scope. Hence, the
