In a town there are probably multiple routes, how to drive or walk or ride
from one house to another. The route from one house to another depends on the
addressing of the houses, but finding a route from one house to another is a
totally separate task from the addressing of the houses. The same with network
traffic. The way computers, programs within the computers, are addressed
is important and an addressing scheme may facilitate or impede computationally
efficient route calculation, but the development of routing algorithms is a
totally separate task from the development of addressing schemes. There can
be multiple routing algorithms for a single addressing scheme.
General Issues with Radio link Based mesh Networks
If the nodes use omnidirectional antennae, then they can be jammed. If the
nodes are based on cellphones or laptops, then the relaying of mesh network
traffic drains their batteries. A citation from
Serval project
2012_05 social studies report: "First,
the range between two phones needs to be extended much further than 60 meters
if the technology is to be used to connect communities to outside services.
Second, the technology must include security measures to ensure that sensitive
information cannot be hacked and misused. If such an incident occurred,
community users would quickly lose their trust in the technology and uptake and
use would be difficult to regain."
