Enhanced-TDOA Measurement for Ad Hoc Networks Positioning
نویسندگان
چکیده
To maintain the Ad Hoc network connectivity and to perform efficient energy communication between several mobile stations (MS), optimized routing algorithms need accurate short-range localization or/and positioning data. Due to indoor propagation, multipath may dramatically increase location budget error and ask for innovative solutions allowing accurate time of flight measurement. An original solution, based on a like Ultra Wide Band (UWB) technology, uses millimeter multitone dual transmission acting like a pulse composite signal and a basic millimeter receiver involving Enhanced Time Difference Of Arrival measurements (E-TDOA). Index Terms ___ E-TDOA, multipath, UWB, millimeter wave, location, channel sounding

Mobility-enhanced positioning in ad hoc networks
This paper discusses and investigates the effects of mobility on positioning of wireless ad hoc networks. We present a Mobility-enhanced Ad hoc Positioning (MAP) scheme, where we leverage on the mobility of nodes within the network. The scheme uses the hop counts information from fixed reference nodes to perform positioning and improves accuracy by using mobile nodes to “bridge” gaps within nei...

We consider the problem of node positioning in ad hoc networks. We propose a distributed, infrastructurefree positioning algorithm that does not rely on GPS (Global Positioning System). Instead, the algorithm uses the distances between the nodes to build a relative coordinate system in which the node positions are computed in two dimensions. Despite the distance measurement errors and the motio...
