| This paper considers the problem of secure communication in Wireless Sensor Networks in the presence of non-colluding passive eavesdroppers. Cognitive networks capabilities such as spectrum sensing, share information and collaboration to optimize the communications can be used to avoid attacks. A collaborative jamming technique is proposed to increase Cognitive Wireless Sensor Networks security and a counter measurement against eavesdropped attacks. Three types of scenarios are defined: attacker location known, attacker location unknown, and attacker and relay co-location. Each new scenario adds a difficulty to the countermeasure to the previous one. Simulations show as Secrecy Outage Probability decreases until 10% with a standard number of relay nodes in the network. As a result, cooperative jamming strategies are seen to be highly effective for increasing the secrecy in Wireless Sensors Networks | |
