CLOE: Cross-Layer Design for Wireless Networks

Cross-layer optimization is an effective mechanism to improve wireless system and network performance and efficiency. Cross-layer optimization is not a new technique, but it can be applied effectively to different wireless technologies to handle different problems without violating the wireless standards. Utility functions are constructed from measurements of the different OSI layers to provide input into our cross-layer optimization engine. ZigBee technology was chosen as the test platform to demonstrate our proposed mechanism.
