“…In their following work [26], systematic evaluations of the multi-BS cooperation gain of the coverage, handover and costs are provided, and they also discussed some BS planning problem formulations with only signal coverage constraints. In [27], the cost of optical fiber backhaul is considered in addition to the BS deployment cost, and the optimal cost efficient inter-BS distance is calculated. However, the above papers do not provide any specific BS planning algorithms.…”

Abstract-In traditional cellular networks, the network planning scheme is imperative for satisfying the coverage and traffic requirement. The rapidly growing number of users in today's cellular networks demands more base stations (BSs) to accommodate the increasing traffic load. The dense deployment results in severe energy consumption, which is often overlooked by existing network planning schemes. In this paper, an energyaware network planning scheme is proposed to reduce the energy consumption of BSs by leveraging the coverage extension functionality of the inter-cell cooperation. The network planning problem is formulated as a mixed integer programming problem, which is solved with the Lagrangian relaxation method. Numerical results show that the energy efficiency can be enhanced by as much as 20% compared with the non-cooperative scheme without violating the QoS requirement. It is also shown that the proposed scheme is robust to the energy consumption structure of the BSs, and thus can be used with various types of BSs.

“…The authors propose a scheme that guarantees the source allocation among all types of traffic. For cost aspect, there are research works that investigate the prices of component and labour cost of different access technologies including the PON technology such as [10] [11] [12]. All of these studies emphasis on the labour cost of fibre installation.…”

“…All of these studies emphasis on the labour cost of fibre installation. For example, the whole cost of installing fibre including labour and cable is up to $20,000/km [10]. It is clear from the aforementioned studies that a lot of works have been done for converging PON and 3G, but the current transition from 3G to 4G implies focusing on 4G networks and how it could cut down the cost of deployment.…”

The necessity to support the rapidly growing high speed broadband services requires the use of latest technologies and quality of service (QoS) control techniques. Two such technologies include Fourth Generation (4G) wireless and New Generation Passive Optical Networks (NG PON). 4G communication technology encompasses both wireless and cellular systems, which aims to provide real-time voice, video and Internet services to the end user with high QoS. Moreover, it offers high throughput and supports mobility. A passive optical network (PON) is a reliable back haul technology, which can provide high bandwidth and is highly cost effective. The combination of 4G with NG-PON creates an access network that is cost efficient, reliable, flexible as well as facilitating mobility and ubiquity. However, this integration has many challenges such as maintaining the QoS of whole network. In this paper, we propose the NG PON as an alternative solution for the point to point fiber in the 4G centralized co-ordinated Multi-Point (COMP) transmission and reception. This architecture is for joint transmission downlink COMP which benefits from the broadcasting transmission in the downlink of PON. Moreover, it serves both fixed and mobile stations. The simulation compares the capital cost of using NG PON against point to point fibre in COMP architecture. The results reveal that up to 80 percent cost reduction can be achieved by using the proposed solution.

“…An optimal ONU-BS placement model was presented in [13], which jointly take BS-User association and resource breakdown assignment into consideration.

Multimedia applications over the Internet, such as IPTV and video-on-demand, have become fast growing applications in recent years. Such applications have stringent quality of services (QoS) constraints in terms of bandwidth, delay, and packet loss. As a consequence, broadband access networks play an important role for multimedia applications. There are two emerging technologies offering both high bandwidth and QoS support, namely Ethernet Passive Optical Network (EPON) and Worldwide Interoperability for Microwave Access (WiMAX). By integrating these two technologies, EPON-WiMAX integrated network can: (1) provide broadband access, (2) support mobile users, and (3) decrease network planning cost and operating cost. Thus, EPON-WiMAX integrated network is an ideal choice for multimedia applications with ubiquitous access. Although EPON-WiMAX integrated network has received growing attentions, however, most of previous works focus on the scheduling and bandwidth allocation in the upstream direction. Therefore, in this paper, we investigate the downlink scheduling and bandwidth allocation problem in EPON-WiMAX integrated networks. The objective of the study is to maximize the system throughput and guarantee the (QoS) so that the requirements of multimedia applications can be fulfilled. We proposed a two-stage downlink packet scheduling and resource allocation mechanism collaborating with application layer forward error correction (AL-FEC). We demonstrated the performance of our approach via simulations. Our simulation results indicated that the proposed mechanism increased the system throughput significantly, especially when AL-FEC is adopted.
