Jointly positioning multiple users in aid of user-to-user distances

2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017
A multiuser positioning algorithm in aid of user-to-user (U2U) distances is proposed in this paper. The cost function is the combination of non-linear least squares (NLS) of time of arrival (TOA) of multiple users and the NLS of U2U distances among users. Particle swarm optimization (PSO) is applied to search the best positions of the multiple users in

2012 Fifth International Joint Conference on Computational Sciences and Optimization, 2012
In this paper we introduce a length constrained user equilibrium model. In our model, people consider two criteria, path time and path length, when selecting their routes. They only travel on "acceptable paths", the paths whose length are not too long for them.
