WSNs are generally heterogeneous distributed wireless radio networks, with little to no manual operation. Sensors or nodes use low power frequencies to conserve energy and prolong battery life. Wireless sensor networks WSNs consist of a group of distributed monitor nodes working autonomously together cooperatively to achieve a common goal. Generally they face many threats, threatening the security and integrity of such networks. Jamming attacks are one of the most common attacks used against WSNs. In this paper, the authors discuss the jamming attack and defense mechanisms proposed by two papers and suggest improvements on those four approaches.
