Abstract
As the ubiquitous computing environment gets more attention and development,
WSN (Wireless Sensor Network) is getting popular as well. Especially, the
development of wireless communication and sensor equipment greatly
contributes to the popularization of WSN. On the other hand, the safety and
security of WSN attracts lots of attention due to such a development and
distribution. The DoS (Denial of Service) attack, which gets more
sophisticated and broadens its domain into various services fields, may have
negative effects on WSN, making it vulnerable to attacks. Since WSN collects
information through sensors that are already deployed, it is difficult to
have its energy recharged. When WSN is under a DoS attack, sensor nodes
consume lots of energy, bringing about a fatal result to the sensor network.
In this paper, we propose a method to efficiently defend against DoS attacks
by modifying routing protocols in the WSN. This method uses a location based
routing protocol that is simple and easy to implement. In the WSN environment
where the location-based routing protocol is implemented, this method
disperses the DoS attack concentration of traffic by using the traffic
deflection technique and blocks it out before arriving at the target
destinations. To find out the number of traffic redirection nodes proper for
this method, we have performed a few experiments, through which the number of
such nodes was optimized.
