Wireless Sensor and Actor Network - Security Analysis
Binodkumar, Malathi Balaji, R. Dbalaji, Ramkumar Lakshminarayanan · Journal of Wireless Networking and Communications · 2014
Wireless sensor and actor networks (WSANs) refer to a group of sensors and actors linked by wireless medium to perform distributed sensing and actuation tasks. In such a network, sensors gather information about the physical world, while actors take decisions and then perform appropriate actions upon the environment, which allows a user to effectively sense and act at a distance. WSANs are exposed to numerous security threats that can adversely act the success of import applications. Although WSANs share many common grounds with sensor networks, it is difficult to apply existing security technologies due to the fact that WSANs contain actor nodes that are resource-independent and mobile. This paper aims to study the security aspects of these networks. It paper first introduces sensor networks, its architecture and working and then presents security related problems, threats, risks and characteristics and then finally security defence measures. Additionally, the paper gives a brief introduction to proposed protocols for sensor network security applications. It also highlights experimental work necessary to make these applications more reliable and robust in the real world.
