This paper discusses various approaches to save power in relay-based cellular networks. We introduce an optimization method based on the Hungarian assignment problem to globally minimize the power-based allocation of relays. We compare this approach with the greedy approach of choosing a relay. We introduce another approach based on the concept of intelligent relays. Here, based on the expected power values of mobiles at the relay’s location, the relay chooses to carry call for a mobile. We show that this approach introduces less intra-cell interference.
