“…But this method will increase the number of APs if a fixed area is given. Another solution is that each AP simply enhances its emission power (Kim et al, 2008;Jung and Vaidya, 2002). But this solution would worsen the signal/radio interference between the two nearby co-channel mobile nodes.…”

Power efficient transmission has received significant attention among cellular network operators to reduce the environmental effects and to maintain profitability. Since the evolved node base station (eNB) is the primary power consumer in the cellular network, endeavours have been made to study eNB power consumption and to find approaches to enhance power efficiency. The concept of multi-hop relay (MHR) network is introduced in 4G and beyond standards to reduce the deployment cost and transmission power while improving the coverage and capacity. Here relay stations (RS) are also deployed by the network operators along with eNBs to maximize the average spectral efficiency per user. But the deployment of RSs is not standardized. Improper RS deployment leads to severe quality loss. In this work, RS deployment based on cost (RDBC) approach is utilized which identifies the RS deployment combinations and deploys different types of RSs to maximize the system quality. Through simulations, it is validated that the proposed approach maximizes the transmission quality, coverage and effectiveness in power consumption and minimizes the deployment cost and interference when compared to many of the conventional RS deployment

“…It has been shown that the subsequent allocation of resources to relays results in inefficient utilization of the available bandwidth and, thus, it is better to let the relays operate simultaneously. In study [5], various issues of cost-effective coverage extension in a multi-hop relay based WiMAX systems have been investigated. The concept of wireless relaying has been considered in [3], and performance results there have shown that multi-hop relaying enables cost-effective enhancement of coverage, user throughput, and system capacity, which is especially suitable for the emerging markets and rural areas.…”

IEEE 802.16j is a wireless broadband networking standard that integrates infrastructure base stations with multihop relay technology. Relay stations can provide substantial gains of coverage area and capacity of the cell compared to a base station alone. In this paper, we introduce an optimization problem of cost-effective relay station deployment for the IEEE 802.16j networks in the case of extending the coverage on the new residential area. First, the coverage area, which is defined as an area where the user has a signal-to-noise value greater than a given threshold value, is calculated. After that, the number of relay stations and their optimal positions which maximize the provider's profit are found, taking into account one-time costs, such as CAPEX and IMPEX, as well as recurring costs, like OPEX. The proposed relay deployment mechanism allows the providers to maximize their own profit if they want to extend the coverage area to attract new customers.
