Paper Abstract:
|
Wireless Sensor Networks (WSNs) are vulnerable to failures that may lead to the disconnection of parts of the network, creating partitions in the network, isolating the sensor nodes. This problem compromises the final results achieved by the WSN operation, as those isolated nodes are not able to deliver their messages to the sink nodes. A way to overcome such problem is to provide an alternative connection to support the connectivity via other types of nodes that repair the connectivity among the sensor nodes. This paper proposes the usage of Unmanned Aerial Vehicles (UAVs) as relay nodes to guarantee the delivery of data produced by WSN nodes on the ground to the end users. Results form simulations of the proposed technique are provided and discussed. |
