Abstract

We introduce a novel application of Particle Swarm Optimization in the mobile computing domain. We focus on context aware applications and investigate the context discovery problem in dynamic environments. Specifically, we investigate those scenarios where nodes with context aware applications are trying to (physically) locate up-to-date context, captured by other nodes. We establish the concept of context quality (an ageing framework deprecates contextual information thus leading to low quality). Nodes with low quality context cannot capture such information by themselves but are in need for “fresh” context in order to feed their application. We assess the performance of the proposed algorithm through simulations. Our findings are quite promising for the mobile computing domain and context awareness in specific. We assess two different strategies for the PSO-based context discovery framework.
