Parameter | Meanings |
---|---|
RDM | Real data message |
FDM | Fake data message |
H(i) | Number of kids node i has |
m(i) | Number of fake messages generated by node i |
ρ | The (average) generation rate of RDM messages per unit of time each node generates |
X × Y | 2 dimensional deployment area (m) |
Real sink | Rs |
Fake sink | Fs |
r 1 | Sensors' communication range |
x (i), y (i) | Location of a node i or a sink i |
N | Total number of nodes in the network |
TPN1 | Largest amount of traffic volume among the traffic volumes generated by the real sink's neighbors |
TPNϵ+ 1 | Largest amount of traffic volume in the traffic volumes generated by nodes from (ϵ + 1) hops from the real sink |
hop (i) | Number of hops forming the routing path from node i to the real sink |
h max | Size of the longest routing path from a source to real sink that is formed over the WSN |
Φ(i, j) | Number of hops from node i to the fake sink j |
Ω(k, j) | Number of hops from a sink k to sink j |
