Distributed Port Scan Detection

Abstract

Humans are constantly inventing new technologies to fulfil their needs. Wireless sensor networks (WSNs) are a still developing technology consisting of multifunction sensor nodes that are small in size and communicate wirelessly over short distances. Sensor nodes incorporate properties for sensing the environment, data processing and communication with other sensors. The unique properties of WSNs increase flexibility and reduce user involvement in operational tasks such as in battlefields. Wireless sensor networks can perform an important role in many applications, such as patient health monitoring, environmental observation and building intrusion surveillance. In the future WSNs will become an integral part of our lives. However along with unique and different facilities, WSNs present unique and different challenges compared to traditional networks. In particular, wireless sensor nodes are battery operated, often having limited energy and bandwidth available for communications.
