Anomaly Detection in Wireless Sensor Networks ◾ 293
Li et al. [55] present a quantitative approach for anomalous node detection in
WSN. is approach is based on data transmission quality (DTQ) functions. e
WSN is divided into several groups. Each SN maintains DTQ table of neighboring
nodes. e DTQ function is given in the following equation.

Here k is an integer. D/E denotes the number of data packets transmitted in
unit energy. STB() represents data transmission stability and P() is the probability
of successfully transmitted packets. e value of DTQ remains constant or changes
smoothly for normal nodes a ...
