Ultra Wide-Band (UWB) Positioning Routing in AD HOC Networks

This paper proposes a positioning routing algorithm for UWB ad hoc networks. The algorithm is deployed in two main scenarios: Multi-Coordinate System (MCS) and Unique Coordinate System (UCS). A Packet Forwarding Zone (PFZ) is proposed to investigate the performance where a limited forwarding region is used. New ideas have been included in the routing algorithm, such as the use of the Davidon-Fletcher-Powell (DFP) algorithm to estimate the position of the locally available beacon nodes, and the Reference Group (RG) concept as formed by suitable nodes with the Reference Group Master (RGM) chosen as elected by the nodes in the RG. The RG group characteristics particularly apply in the UCS case. In addition, the performance of Direct Method (DM) and DFP position estimation algorithms are also analyzed.
