Multi-hop relaying is an important concept in future generation wireless networks. It can address the inherent problems of limited capacity and coverage in cellular networks. However, most existing multi-hop relaying architectures waste energy. In this paper, our goal is to find a power-effective multihop relaying architecture, since the problem of coverage extension may occur in the given target service area where users' traffic density is relatively low or moderate, this paper introduces several popular topologies and the corresponding coverage extension methods for each case. Further, sets up the optimized mathematical model and obtain the simulation results which show that Type-D is the best topology which consumes less power than Type-A, Type-B and Type-C.
