1. INTRODUCTION
Sensor networks using distributed wireless technology are utilized in many applications, such as health monitoring
system, building or infrastructure access systems, disaster relief and tsunami warning systems. Some of these applications
lack security due to resource constraints, thus, resulting in reduced Quality of Service (QoS). In resource constrained
network such as WSN, traditional security schemes cannot be applied. Hence, need for new security measures
to maintain network functionality without sacrificing performance becomes a necessity. In this paper, different jamming
attack on WSN is considered, and a defense mechanism is proposed.
In WSN, a multitude of wireless sensors are interconnected by means of RF communication links. The functionality
of the nodes in this application include sensing, collecting and distributing dynamic information within the network.
Energy usage is a key issue as the sensors are typically

1 。导言
传感器网络采用分布式无线技术是利用在许多应用中，如健康监测
体制，建设或基础设施的接入系统，救灾和海啸预警系统。部分这些申请
缺乏安全受资源限制，因此，导致降低服务质量（ qos ） 。在资源约束
网络如wsn ，传统安全计划不能适用。因此，需要采取新的保安措施
要保持网络的功能又不牺牲性能，成为一种必要。在本文中，不同的干扰
攻击wsn是考虑了，并在一个防御机制。
在wsn ，众多的无线传感器是相互联系的方式射频通讯联系。功能
该节点在这种应用包括传感，收集和分配动态的信息网络。
能源的使用是一个关键问题，由于传感器是典型的微型和无线与有限的内存和功能，给出了
这一事实，即电池（ y ）的具有有限的电力供应。因此，出现困难，在计算[ 2 ] 。网络或
节点可受多种拒绝服务攻击，包括那些，迫使节点必须在闲置或待机模式。这
影响绩效的节点和网络。在最坏的情况下，被攻击的节点继续沟通，其
邻居终于耗尽其所有的权力，并宣布自己死了，从而降低了网络的覆盖范围。因此，
wsn需要可变最小等待期（网络设置需要进行调整） 。沟通环节
这种不可预知的环境（节点失效）保存功能中的一个强有力的路由算法。在这
提出了一种新颖的方法。代理商利用传感器节点的信息可用于预测或预期干扰
攻击所用的关键性能参数。
