Executive Summary

The paper deals with efficient location-based decision supporting content distribution to mobile groups. The authors consider the case where a set of Information Dissemination Devices (IDDs) broadcast a limited amount of location-based information to passing mobile nodes that are moving along well-defined paths. They develop a novel model that captures the main aspects of the problem, and define a new optimization problem they call MBMAP (Maximum Benefit Message Assignment Problem). They study several variants of this problem in the case where the IDDs are cooperative and in the case where they are not. They develop new approximation algorithms for these variants and then focus on the practical effects of using them in realistic networking scenarios.
