Jamming Attack Against Structure-free of Wireless Sensor Networks

Structure free Wireless Sensor Network is a
type in which the transfer of the data depends on the
resources of the sensor nodes. Energy and memory
utilization represent the main resources of this type of
wireless sensor networks. The transfer of data in WSNs
can be interrupted by launching special jamming nodes
at the field. However, the life time of the jamming nodes
depends on the jamming models used for such purpose.
In this paper, we study the effect of different types of
jamming models onthe performance of the structure free
WSNs by using appropriate computer simulation tests.
The results show that the random jammer with (25%)
saving time is the most effective jamming model against the
structure free wireless sensor networks as compared with
the other jamming models.
