Wireless Sensor Networks (WSN), as an emerging technology facing numerous challenges. Sensor nodes often have resource limitations and are also vulnerable to physical attacks or node compromises. Because projected applications for wireless sensor networks range from intelligent applications such as traffic monitoring to critical military applications such as measuring concentration levels of gas in battlefields, safety in sensor networks becomes a primary concern. In sensitive applications, it is imperative to continuously monitor the transient state of the system rather than steady-state observations and take the necessary preventive and corrective actions. Generally, networks are prone to being attacked by opponents intent on disrupting system operation by compromising sensor nodes and injecting false data into the network. Therefore, it is important to protect the sensor network against false data injection attacks. In this paper, it is proposed to use a new efficient cooperative bandwidth authentication system (BECAN) to filter fake injected data based on Bloom Filter.
The wireless sensor network is usually composed of a large number of sensor nodes that are interconnected through wireless links to perform distributed detection tasks. Each sensor node is low cost but equipped with sensors, data processors and communication components required. The wireless sensor network is a collection of nodes organized in a cooperative network. Each node consists of processing capacity with one or more microcontrollers, CPUs or DSP chips and can contain multiple types of memory or flash memory containing program or data. Each node has an RF transceiver usually with a single Omnidirectional antenna, and a power source such as batteries and solar cells, and accommodates several sensors and actuators. Advances in microelectronics and wireless communications have led to the creation of wireless sensor network (WSN) technology. This technology has many applications including various environmental monitoring. A primitive goal of WSNs is to answer the questions by collecting sensory data from the deployed sensors.
