摘要：A wireless sensor network (WSN) is a network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. Data security is essential for these mission-critical applications to work in unattended and even hostile environments. So, we have to take providing desirable data security, that is, confidentiality, authenticity, and availability, in wireless sensor networks (WSNs) as a challenge. WSN consists of a large number of sensor nodes. These sensor nodes are mini, low-cost, smaller memory sizes and low bandwidth. Existing security designs are vulnerable to many types of Denial of Service (DoS) attacks, such as report disruption attacks and selective forwarding attacks. In this paper, we seek to overcome these vulnerabilities for large-scale static WSNs.
