Secure Distributed Detection In Bandwidth-Constrained Wireless Sensor Networks, Reza Soosahabi
LSU Master's Theses
Utilizing wireless sensor network (WSN) is a novel idea in a variety of applications. However, the limited resources allocated to the sensor nodes make the design of WSNs a challenging problem. We consider the problem of hypothesis testing in a bandwidth-constrained, low-power wireless sensor network operating over insecure links. Sensors quantize their observations and transmit their decisions to an intended (ally) fusion center (AFC) which combines the received messages to detect the state of an unknown hypothesis.
In many applications the sensor messages are vulnerable to unauthorized eavesdropping. The scarce bandwidth and processing power for the sensors rule out the …
