With the development of mobile ad hoc network (MANET), quality of service (QoSj routing becomes more and more important. Power control scheme will decrease the interference between paths and conserve energy at hosts. But, the bandwidth evaluation will be more difficult due to the dynamic transmitting power. In this paper, we propose a multi-path QoS routing with power control (MQRPC) in TDMA-based MANETs. MQRPC can provide QoS guarantee and conserve energy by power control, which takes into account both the transmit power and the residual energy of the hosts along the multiple disjoint paths from a source to a destination. Simulation results show that MQRPC has good network performance and balances the energy consumption of hosts.
