Wireless Sensor Networks (WSN) are rising as new stage in the IT ecosystem and in rich field of active research involving hardware and system design, distributed algorithms, networking, security and social factors. Security is a term used about the characteristics of integrity, authentication, privacy, anti-playback, and non-repudiation attacks against wireless sensor networks. Of the various possible security threats encountered in a Wireless Sensor Network (WSN), this paper is specifically concerned in fighting against two types of attacks: Compromised Node (CN) and Denial Of Service (DOS), which generates black holes. General classic multipath routing methods are vulnerable to these attacks, due to their deterministic nature.
