In this paper, we tend to take a holistic approach to the protocol design design in multihop wireless networks. Our goal is to integrate various protocol layers into a rigorous framework, by concerning them as distributed computations over the network to unravel some optimization problem. Completely different layers perform distributed computation on different subsets of the choice variables using local data to realize individual optimality. Taken together, these native algorithms (with respect to different layers) achieve a global optimality. Our current theory integrates 3 functions—congestion control, routing and scheduling—in transport, network and link layers into a coherent framework. These 3 functions interact through and are regulated by congestion worth so as to attain a world optimality, even during a time-varying environment. At intervals this context, this model allows us to systematically derive the layering structure of the varied mechanisms of different protocol layers, their interfaces, and the management info that has got to cross these interfaces to achieve a certain performance and robustness.
