- W20800732 abstract "Efficiently transmitting data in wireless networks requires joint optimization of routing, scheduling, and power control. Also, transmitting data to multiple destinations (multicasting) in an optimal way typically involves the solution of difficult combinatorial optimization problems. To avoid such difficulties, we use the concept of network coding to design an optimization problem for the problem of transmitting multiple multicast messages through a time-slotted multihop wireless network whilst allowing multipath routing. Apart from the mathematical model, we introduce a block co-ordinate descent algorithm that uses information about active constraints and the decoupled nature of the problem, and prove its convergence to a global optimum under certain assumptions. Numerical examples of wireless mesh backhaul networks with fixed nodes show that the algorithm rapidly provides optimal solutions in networks with no interference, and good solutions in a range of more challenging circumstances." @default.
