Indoor positioning for mobile phone is important for many applications.The widely used mobile phone indoor positioning technologies need to pre‐located anchor nodes,or collect fingerprint for the indoor environment.Peer‐to‐Peer Hybrid Cooperative Positioning (P2P‐HCP) is a novel indoor positioning technology to provide reliable,GNSS‐like navigation performance in hostile,GNSS‐challenged environments.A new P2P‐HCP algorithm is proposed for mobile phone indoor positioning.In this algorithm,short‐range communication is used to exchange location information.A novel data fusion algorithm is proposed to fuse both navigation satellite information and located neighboring phones’ information to estimate position.Simulation result shows that the proposed algorithm offers a good performance in accuracy and coverage in indoor environment without any priority information or pre‐located anchor nodes.
