Abstract
Wireless sensor and actor networks are fully automated. Actor nodes are inducted to communicate with sensor nodes directly and reduce the communication delay caused by base station or sink nodes. Sometimes, the actor node is directly accessible without the involvement of any control room. The actor node is responsible for taking a prompt action against the reported event by a sensor node. For secure communication, it is essential that sensor and actor nodes be aware of their existing location and the data must be encrypted before transmission. Due to energy constraints, secure localization in wireless sensor networks is a hot issue. To date, the researchers have proposed many approaches for localization of sensor nodes in the network. In this paper, we provide new insights for secure actor directed localization technique in wireless sensor and actor networks. A secure connectivity based localization (CBL) approach for sensor and actor nodes localization is presented. The proposed approach helps to locate a sensor node efficiently and effectively. We have also decreased the possibility of attacks and the registration of attacker nodes with other legitimate nodes in the network. The proposed technique prevents man-in-the-middle attacks and securely delivers data to the destination.
Highlights
Wireless sensor network (WSN) is a collection of different sensor nodes which sense certain information from its surrounding and transfer it for further processing to one or more interested nodes called sinks
In a fire handling system, the actors need to turn the water sprinklers on after receiving a report of fire. This leads to the emergence of wireless sensor actor networks (WSANs) [1, 2], which are a substantial extension of sensor networks, involving coexistence of sensors and actors in the same network
Lazos and Poovendran [30] proposed secure and robust localization. They identified the problem of verifying the location claim of a node, known as location verification, in wireless sensor networks (WSNs)
Summary
Wireless sensor network (WSN) is a collection of different sensor nodes which sense certain information from its surrounding and transfer it for further processing to one or more interested nodes called sinks. Due to insecure communication between sensor and actor nodes, any attacker node can take part in this communication and later on become the legitimate member of the network To avoid such types of attacks in Khan et al.’s [10] work, we proposed a secure localization technique where sensor and actor nodes will first encrypt their data with an efficient predecided algorithm. This technique will prevent the attacker nodes registration as well as intervention in communication among sensor and actor nodes.
