Based on the studies of routing algorithms in WiMAX multi-hop networks, a path selection algorithm considering energy conservation for mobile stations is proposed. And the path selection algorithm based on signal-to-noise ratio is improved to reduce energy consumed by mobile stations. The simulation results show that the energy-efficient routing algorithm for mobile stations can reduce the total energy consumption, taking up more system resources. The improved routing algorithm based on signal-to-noise ratio can also reduce the total energy consumption
