A web-based pervasive recommendation system for mobile tourist guides
TL;DR: The concept of ‘context-aware rating’ is introduced, whereby user ratings uploaded through WSN infrastructures are weighted higher to differentiate among users that rate POIs using the mobile tourist guide application while onsite and others using the Internet away from the POI.

Distributed Wireless Sensor Network Localization Via Sequential Greedy Optimization Algorithm
TL;DR: A greedy optimization algorithm, named sequential greedy optimization (SGO) algorithm, is presented, which is more suitable for distributed optimization in networks than the classical nonlinear Gauss-Seidel algorithm, a unified optimization framework is proposed for both range-based localization and range-free localization, and two convex localization formulations are obtained based on semidefinite programming (SDP) relaxation techniques.
