Power consumption of mobile terminals (MT) is a critical design concern in a wireless network. Provisioning of quality of service (QoS) for multimedia traffic in wireless networks is complicated due to user mobility and limited wireless resources. Next generation systems evolves to those that include dynamic adaptation to traffic and QoS needs. In this paper, we propose QoS constrained minimum-power cellular ad hoc augmented network architecture (QCMP CAHAN) for next generation wireless networks. The QCMP CAHAN is a hybrid architecture, in which each MT of CDMA cellular networks has CDMA ad hoc communication capability. The proposed OCMP CAHAN architecture has good scalability and high reliability. In the QCMP CAHAN, the optimal minimum-power routes can he found under QoS constraints (bandwidth, packet-delay, or packet-error-rate constraint). We show that the total energy consumed by the MTs is lower in the case of QCMP CAHAN than in the case of pure cellular networks but the end-to-end delay is higher
