A pricing mechanism for Femto Base Stations*
نویسندگان
چکیده
We denote by Q the reference area of size Q m2. Our problem is to fully cover the area and to provide certain level of QoS for users. There are two types of Base Stations (BS) that can be used for this purpose. Macro-BSs that have large transmission ranges but their energy consumption is high, and Femto-BSs that have smaller transmission ranges and relatively smaller energy consumption. Telecoms service providers have full control over functionality of Macro-BSs, while Femto-BSs are acting more phazy and are controlled by home service providers. Hence, from the point of view of a service provider, Femto-BSs are unreliable. In practice, the full coverage would be provided by reliable Macro-BSs and Femto-BSs would be mainly used to enhance the level of QoS in the network. As discussed above, telecoms service providers have not control over functionality of Femto-BSs. However, they can motivate home service providers to cooperate with them (e.g. activate their FemtoBSs) by porpoising a reasonable price for service they provide. A home service provider can then evaluate its utility according to the price proposed by the telecoms service provider and decide to cooperate if it gets a positive utility. In this draft, we propose a pricing mechanism and evaluate the behavior of home service providers (i.e., the number of active Femto-BSs) for a given price. We mainly focus our attention on Nash equilibrium analysis.

Network Configuration for Two-Tier Macro-Femto Systems With Hybrid Access
In this paper, we study uplink network configuration in a two-tier macro-femto heterogeneous system with hybrid access control. We consider a system where one macro base station and a cluster of adjacent femto base stations together serve a number of mobile users. In this system, base stations and users make decisions in various network configuration processes with different optimization object...
متن کاملAnalysis of Handover Decision with Adaptive Offset and Link Quality Threshold in Next-Generation Hybrid Macro/Femto-cell Networks
Femto base stations are usually installed in the region of macrocells in next-generation hybrid macro/femto-cell networks, and the transmit power of macro base stations is much larger than that of femto base stations. Because the conventional handover decision is only based on the received signal strength (RSS), user equipments near the center of macrocells hardly camp on femtocells, even if th...
متن کاملPerformance Analysis of Energy-Efficient Home Femto Base Stations
The energy consumption of home femto base stations (BSs) can be reduced, by turning off the Wi-Fi radio interface when there is no mobile station (MS) under the coverage of the BSs or MSs do not transmit or receive data packet for long time, especially in late night. In the energy-efficient home femto BSs, if MSs have any data packet to transmit and the Wi-Fi radio interface in off state, MSs w...
متن کاملSum-rate maximization of OFDMA femtocell networks that incorporates the QoS of macro mobile stations
This paper proposes a power allocation scheme with co-channel allocation for a femto base station (BS) that maximizes the sum-rate of its own femto mobile stations (MSs) with a constraint that limits the degradation of quality of service (QoS) of macro MSs. We have found a closed-form solution for the upper limit on the transmission power of each sub-channel that satisfies the constraint in a p...
