摘要：Wireless Sensor Network(WSN) is one o f the most important and unique applications. On the contrary to traditional network architecture, WSN does not require a fixed network infrastructure; every single node works as both a transmitter and a receiver. Nodes communicate directly with each other when they are both within the same communication range. Otherwise, they rely on their neighbors to relay messages. The self-configuring ability of nodes in WSN made it popular among critical mission applicatio ns like military use or emergency recovery. However, the open medium and wide distribution of nod es make WSN vulnerable to malicious attackers. In this case, it is crucial to develop efficient intrusion -detection mechanisms to protect WSN from attacks. With the improvements o f the technology and cut in hardware co sts, we are witnessing a current tren d of expanding WSN into industrial applications. To adjust to such trend, we strongly believe that it is vital to address its potential security issues. In this paper, we propose and implement a new intrusion -detection system named Enhanced Adaptive ACKnowledgment (EAACK) specially designed for WSN. Compared to contemporary approaches, EAACK demonstrates higher malicious-behavior-detection rates in certain circumstances while does not greatly affect the network performances. In EAACK scheme the wireless sensor network is going to be analysed in terms of Bit error rate (BER).
