Security has become a primary concern not only for researchers, but also for many users. Wireless Sensor Networks (WSNs) are susceptible to various kinds of attacks, so the need to protect such networks has been increased. There are a number of challenges in WSN security design. Resource constraints such as the ability of processing, low battery life, small memory size and unsecured transmissions make various attacks more dangerous for these networks. Our attention of this paper concentrates on the most typical routing attacks and their capabilities which influence network layer. The attackers can potentially compromise one or more of security goals of the network they attack. This paper is expressing a comparison between routing attacks to find the purpose of the attackers on WSNs' functionality. It classifies and compares them extensively based on different features such as goals, the threat nature, attack function, WSNs' threat site and according to disruption of the route or consumption of the resources. This paper also gives a better understanding of future direction for researchers for designing secure WSNs.
