Abstract
Self-organizing geolocation system does not depend on infrastructure, can build coordinate system automatically and calculate reference point coordinates position, has very high application value in emergency situations. Geolocation service alone often cannot meet all application requirements, while multiple service fusion can improve the practicability of the system. In this paper, we design a multiple service fusion self-organizing geolocation system–MLOC, in addition to the geolocation service, it can also provide voice communication, short message communication and elevation measurement services. This paper deeply analyzes the challenges for multiple service fusion mechanism and self-organization accurate geolocation mechanism; design an unpreemptible hierarchical scheduling mechanism and TDMA/CSMA time slot allocation strategy to solve the problem of multiple services fusion; propose a self-organizing accurate geolocation mechanism based on maximum likelihood centroid localization algorithm; build up a set of prototype MLOC system and verify the MLOC solution through the actual test.
