Attacks and Countermeasures in Wireless Sensor Networks

Today wireless sensor networks (WSN) play an important role in most recent applications such as the internet of things, smart grid, VANET, and underwater sensor networks. Security is a fundamental aspect in WSN. However, WSN suffers from various constraints such as unsecured communications, fault tolerance, and limited resources, which make security a challenging task. In this paper, we present a survey on different attacks in WSNs and their corresponding countermeasures.
