Martin Victor K, K. Ramalakshmi . A Probe on Localization Techniques in Wireless Sensor Networks. International Journal of Computer Applications. 61, 13 ( January 2013), 40-43. DOI=10.5120/9992-4843
Coverage in wireless sensor networks is typically defined as a determination of how correctly and for how long the sensors are proficient to monitor the physical space. It can be taken as the consideration for evaluating the quality of service. Since sensors are spread in a random manner, one of the primary issues in wireless sensor networks is the coverage problem. It is an issue which is to be determined whether a region is sufficiently covered by a set of sensors. The deployment and activation of static nodes along with the density control and trajectory of mobile nodes are major concerns of the coverage problem and the same should be dealt upon through competent localization techniques. This work analyzes localization based on the hardware, design and techniques under several classifications and finally outlines the current state of contemporary localization techniques accompanied with the inherent design tradeoffs.
