Abstract
A novel approach to opportunistic positioning based on timing measurements is presented. The asynchronous radio transmissions from fixed stations and from mobile GPS-equipped nodes are jointly exploited to cooperatively localize a blind node. To this end, a weighted least-squares (WLS) estimator is proposed; its effectiveness is illustrated via simulations in a realistic scenario.
