Abstract
Indoor location-based service (LBS) has various
challenges, including that of numerous service lookups being
requested concurrently and frequently from several locations,
and that the network infrastructure needs to support high
scalability, such as inserting or deleting network nodes anytime
and anywhere. In general, indoor LBS resources are generally
located in close proximity to the requested point. However, a
traditional centralized LBS system needs to maintain a
geographical map of the entire building or complex in its
central server, which can cause low scalability and traffic
congestion. This paper presents a self-organizing and fully
distributed indoor LBS platform through regional cooperation
among devices, and a service lookup algorithm that searches
for the shortest physical path to the service resource. An
evaluation of the performance of the proposed platform has
been compared to the traditional centralized method regarding
the service turnaround time according to the number of
concurrent lookup increases.
