With the emergence of powerful processors and complex applications, wireless communication devices are increasingly power hungry. While there exist several solutions to provide transmission power management in cellular wireless networks and ad hoc wireless networks, it remains an open problem in recently proposed hybrid wireless networks. The Multihop Cellular Network (MCN) and Multi Power Architecture for Cellular network (MuPAC) are instances of hybrid wireless networks, which are proposed to increase the system throughput and spectrum reuse by infusing multihop radio relaying mechanism into the infrastructure-based wireless networks. This paper proposes a novel variable power optimization scheme for the hybrid wireless network architectures such as MCN and MuPAC in order to optimize the power consumption at a mobile node without losing the throughput advantage gained by the multihop scheme. Extensive simulation results show 10% to 15% improvement in power consumption and system throughput which is significant in case of power constrained mobile nodes.
