System design and numerical analysis of adaptive resource discovery in wireless application networks

In this paper, we propose an adaptive resource discovery method in heterogeneous wireless application networks. The adaptive method uses either centralized mode or flooding mode to discover available resources according to different network status. The proposed adaptive method is used to reduce energy consumption in resource discovery process. We establish theoretical energy model for both modes. A heuristic algorithm is designed to implement the proposed adaptive method. It is also proved to be energy efficient through extensive evaluations.
