Abstract
Crises generate intense need to communication not
just as a panic reaction to crisis, but also due the critical need
for communication in order to better coordinate during response
activities. In the afterward of a disaster, the lack of resources
to handle this increase of data, due to the fragility of network
infrastructures, leads to network congestion or overload. The
results is that critical data are prevented from reaching decision
makers, which has a direct impact on situational-awareness. To
overcome this problem, we propose a new cross layer architecture
for Wireless Mesh Network with a twofold objective: one, to
include a filtering system able to identify the most critical data
and two, to propose a routing layer with the capacity to prioritize
these data while ensuring the stability and throughput optimality
of the whole network. The proposed solution combines both
by proposing an adjustable and fully distributed version of the
high throughput efficient Backpressure routing protocol, with a
geolocation and role-based filtering and prioritizing system. Both
components collaborate in a way to identify and send most critical
data, using a lower end-to-end delay, without however starving
less critical data. Extensive experiments, using NS-3 simulator,
are used to validate the proposal and confirm the high impact
of the introduced ideas
