The most common possible threat is DDoS. These attacks flood target with plentiful fake packets in order to drain the battery, prevent the genuine packets to pass thru and thwart the legitimate user to get the desired response. In this research article, we propose a detection and defense mechanism using packet filtration which deploys mitigation constraints to save the wireless sensor networks from the causes of DDoS. | International Journal of Computer Networks and Communications Security VOL. 5, NO. 12, DECEMBER 2017, 277–284 Available online at: E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) Detection and Defense against Distributed Denial of Service Attack Using Packet Filtration in Wireless Sensor Networks Tariq Ahamed Ahanger1 and Abdullah Aljumah2 1, 2 College of Computer Engineering and Sciences, Prince Sattam Bin Abdulaziz University, Saudi Arabia 1 , 2aljumah@ ABSTRACT Ranging from household to health to battlefield plays a significant role in many useful applications. Due to the distinctive feature of region and selforganizing, WSN (regarded as resource constraint type of network), is formed by a group of sensor nodes to detect physical phenomenon like light, heat, pressure with processing ability. Due to their resource constraint characteristics of limited memory and energy they are vulnerable to many cyber threats and attacks. The most common possible threat is DDoS. These attacks flood target with plentiful fake packets in order to drain the battery, prevent the genuine packets to pass thru and thwart the legitimate user to get the desired response. In this research article, we propose a detection and defense mechanism using packet filtration which deploys mitigation constraints to save the wireless sensor networks from the causes of DDoS. Keywords: DDoS, WSN, Cyber Attack. 1 INTRODUCTION The Wireless Sensor Network or WSN as it is used frequently are easy to adopt, easy to customize and easy to maintain solution. Their lower cost of implementation and effectiveness has made them more useful in Armed Forces, Industrial Manufacturing, and Terrestrial Monitoring and even in Personal Health care, but these same features of WSN has made them vulnerable to various security threats [1]. Different deployments requires different security standards and mechanism notably confidentiality, integrity and .
