protocol was chosen and augmented with functionality to guarantee data delivery.
The RUDP protocol provides windowing, congestion control, in order delivery,
and over buffering. These are not necessary features in our data collection scenario
and we instead chose a simpler UDP mechanism.
Conclusion
This paper describes the design and implementation of a reliable sensor data
collection network for sparsely deployed sensors. A meshed ad hoc network of
ground nodes and small, fast moving UA is used to gather sensor information and
hand them over to SMS. The unique contributions of the conducted research are
the control of the UA solely through a meshed ad hoc network, the reliable
forwarding of single event packets from sensors to multiple monitoring stations
through the intermittently connected network, and the demonstration of autono-
mous plane operations based on network and environmental parameters. The
baseline of the system is implemented. A one-week experiment showed a robust
system with some straightforward communications from front to backend of the
system. The modularity of this system should enable progressive development of
the research areas. We believe this system design will greatly enhance quality of
life, health, and security for those in assisted living communities.
