Access Point Placement for Context-aware System
The location information of the mobile user is an essential contextual element in a context-aware system. We investigated the optimal access point (AP) placement to enhance positioning accuracy, and presented a Being Away From Obstacles (BAFO) algorithm designed for context-aware systems using Received Signal Strength (RSS)to position objects. With BAFO algorithm, we can place APs by considering the circumstances such as the distribution of obstacles. The main objective of BAFO algorithm is to place APs away from obstacles, therefore minimizing the influence of obstacles on the signal strength.We made experiments to compare BAFO algorithm with hexagonal algorithm. Our conclusion is that BAFO algorithm is simpler and more effective.
