Center node: "distributed topology design for network coding deployed large scale sensor networks"
  Abstract: In this paper, we aim to design a distributed solution to topology formation problem of large- scale sensor networks with multi-source multicast flows. We propose a distributed solution based on game-theoretic approaches in conjunction with network coding. While it is NP-hard to find an optimal topology for network coding deployed multi-source multicast flows, we propose an algorithm that requires significantly low computational complexity. We formulate the problem of distributed network topology formation as a network formation game by considering the nodes in the network as players that can take actions for making outgoing links. We show that the proposed game, which consists of multiple players and multicast flows, can be decomposed into independent link formation games played by only two players with a unicast flow. It is guaranteed that the proposed algorithm is converged, i.e., a stable network topology can be always formed. Our simulation results confirm that the computational complexity of the proposed solution is low enough for practical deployment in large-scale sensor networks.
