摘要：Mutual Communication (MC) allows save power and extend transmission coverage. However, prior research work on topology control considers MC only in the aspect of energy saving, not that of coverage extension. We identify the challenges in the development of a centralized topology control scheme, named Mutual Bridges, which reduces transmission power of nodes as well as increases network connectivity. Multiple nodes to simultaneously transmit the same packet to the receiver so that the combined signal at the receiver can be correctly decoded. Since MC can reduce the transmission power and extend the transmission coverage, it has been considered in topology control protocols. However, prior research on topology control with MC only focuses on maintaining the network Connectivity, minimizing the transmission power of each node, whereas ignores the energy-efficiency of paths in constructed topologies. This may cause inefficient routes and hurt the overall network performance. In this paper, to address this problem, we introduce a new topology control problem: energyefficient topology control problem with mutual communication, and propose two topology control algorithms to build mutual energy spanners in which the energy efficiency of individual paths are guaranteed. Simulation results confirm the nice performance of the proposed algorithms.
