Resource allocation between exploration of emerging technological possibilities and exploitation of known technological possibilities involves a delicate trade-off. We develop a model to represent this trade-off under the time-pressing situation where the firmÕs existing basis of survival is constantly challenged by competitorsÕ innovation and imitation.

OFDM techniques can be exploited to assist random access contention resolution, which can greatly improve random access efficiency. A cross-layer design method is proposed, where the OFDM-based physical-layer (PHY) signal processing and the MAC-layer packet scheduling are jointly designed and optimized. By this method, contentions can be completely(More)
