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 the authors' Cross-Layer Optimization Engine. ZigBee technology was chosen as the test platform to demonstrate their proposed mechanism. There are a number of short range wireless standards that are utilized today. However wireless standards currently used in this environment are suboptimal in the areas of dynamic information technology capabilities, power consumption, survivability, and efficiency.
