摘要：The global applicability of the wireless technology for communication between devices has altered the entire framework for networks. Mobility of the devices yet allowed to access the services and flexibility are the stated advantages. But still the security measures need additional methodologies to prevent the illegitimate usage and attack to the legitimate users. The Denial of Service attacks (DoS), the most widespread attack to the wireless network requires great concern and resilient mechanisms. This paper discusses the motive and modes of the Denial of Service attacks and their proposed defensive mechanisms. Jammers are the devices with power efficient and easily applicable advancements to extinguish the available bandwidth of the medium. The legitimate users are blocked from their turn of service which the attacker intends. Several defense mechanisms have tried to mitigate the attacks and identify the attacking node, achieving a close success but not completely. The attackers tend to find a new mode of attack every time a defense mode is activated
