Localization

Localization in sensor networks refers to the fundamental problem of estimating the location of sensory nodes in an adhoc network. While centralized algorithms allow the use of sophisticated mathematical algorithms resulting in higher accuracy, data transfer from every sensor node to the base station results in high bandwidth and power requirements. For this reason beacon based distributed methods are rather more popular in localization. A testbed of multiple base stations with relatively higher computing capacities (called beacons) is needed to aggregate the data locally .
