Localization in Wireless Sensor Networks: A review
نویسندگان
چکیده
Various advancement in wireless communication and electronics technologies have enabled the development of low cost, low-power, multifunctional sensor nodes that are small in size and are able to sense, process data and communicate with each other in short distances wirelessly. A continuous growth in both applications and interests of wireless sensor network have witnessed recent years. A brief introduction of Wireless sensor network (WSN) and its localization techniques is provided. WSN have been considered as promising tools for many location dependent applications such as area surveillance, search and rescue, mobile tracking and navigation, etc. In addition, the geographic information of sensor nodes can be critical for improving network management, topology planning, packet routing and security. In this review paper, we present the comprehensive study of WSN and its localization techniques. Keywords– Wireless Sensor Network, Ad Hoc Network, Anchor Node, GPS, Localization Techniques
