We propose a novel algorithm for cooperative localization in wireless networks where relative node distances are available. The proposed algorithm is a trimodal version of variational message passing (VMP). Compared to VMP and bimodal VMP algorithms, the so called tri-VMP algorithm features better localization accuracy for almost the same complexity and cost. This is supported by simulations and measurements...
In wireless systems, localization is still an important challenge to ensure innovative based services solutions. In this paper, a novel localization algorithm which intends to improve robustness and accuracy of previous work based on regression tree is proposed. The suggested approach is a learning based ensemble technique which combines several regression trees. Anchor selection procedure is associated...
