Minimum cost optimization for multicast with network coding has attracted great research interests. In this paper, based on an information model that differentiates intermediate nodes in a multicast network into network coding, routing or replicating nodes, a method is developed to solve the minimum energy cost multicast problem in wireless networks. Besides transmission energy, many other important...
We consider wireless mesh networks, and exploit the inherent broadcast nature of wireless by making use of multipath routing. We present an optimization framework that enables us to derive optimal flow control, routing, scheduling, and rate adaptation schemes, where we use network coding to ease the routing problem. We prove optimality and derive a primal-dual algorithm that lays the basis for a practical...
