    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (4538 KB)

    Location awareness is important in many wireless sensor networks. In sensor networks because of the size, weight, battery life and price some nodes (e.g. GPS-equipped nodes) are self-located but all other nodes have to determine their locations by communication with location-aware neighbors. The classical distance-based technique for location determination is triangulation/lateration (referred to ... View full abstract»
