Jeong SY, Jo HG, Kang SJ - Sensors (Basel) (2015)

Bottom Line: This paper proposes a self-organizing and fully distributed platform for iLBSs.The proposed self-organizing distributed platform provides a dynamic reconfiguration of locality accuracy and service coverage by expanding and contracting dynamically.In order to verify the suggested platform, scalability performance according to the number of inserted or deleted nodes composing the dynamic infrastructure was evaluated through a simulation similar to the real environment.

ABSTRACT
Indoor location-based services (iLBS) are extremely dynamic and changeable, and include numerous resources and mobile devices. In particular, the network infrastructure requires support for high scalability in the indoor environment, and various resource lookups are requested concurrently and frequently from several locations based on the dynamic network environment. A traditional map-based centralized approach for iLBSs has several disadvantages: it requires global knowledge to maintain a complete geographic indoor map; the central server is a single point of failure; it can also cause low scalability and traffic congestion; and it is hard to adapt to a change of service area in real time. This paper proposes a self-organizing and fully distributed platform for iLBSs. The proposed self-organizing distributed platform provides a dynamic reconfiguration of locality accuracy and service coverage by expanding and contracting dynamically. In order to verify the suggested platform, scalability performance according to the number of inserted or deleted nodes composing the dynamic infrastructure was evaluated through a simulation similar to the real environment.

sensors-15-12156-f005: Protocols to support iLBSs in the proposed platform.

Mentions: In order to support the proposed services, specific designed protocols for localization of the mobile devices and between numerous devices and SLiM Hubs are needed. As shown in Figure 5, the proposed self-organizing distributed platform works using three protocols that were developed with our previous research: location-ID exchange & asynchronous message delivery (LIDx & AMD), location-based service discovery protocol (LSDP), smart device to SLiM Hub service lookup protocol (SSLP).
