“…One direction is to examine DBA approaches providing specific quality-of-service assurances to some traffic classes, while providing overall low average delays to best effort traffic. Another direction is to examine efficient approaches for interfacing long-reach PONs with complementary networks, such as wireless local and access networks [56]- [59] as well as metropolitan and wide-area networks [60]- [63].…”

Abstract-Multi-thread polling (MTP) with offline scheduling and offline excess bandwidth distribution has recently been proposed to overcome the long propagation delay of long-reach passive optical networks (LR-PONs). In this paper, we propose a complementary MTP approach with online scheduling and online excess bandwidth distribution. We evaluate the throughput-delay performance of offline and online MTP against offline and online singlethread polling (STP) with excess bandwidth distribution as well as double-phase polling (DPP) with excess bandwidth distribution. We find that online MTP and STP as well as DPP give significantly lower average packet delays than offline MTP.Index Terms-Delay evaluation, dynamic bandwidth allocation, excess bandwidth distribution, long-reach PON (LR-PON), multithread polling (MTP).

“…Ranaweera et al [5] have proposed a loop back architecture with the help of a remote active node in a tree based EPON to reduce HO latency. However, this architecture requires active remote nodes (RNs), which heavily increase the OPEX.…”

“…Ethernet/Gigabit passive optical network (EPON/GPON) can be used to construct the optical backhaul due its passive distribution and low operational cost. For the wireless last mile, different candidates have already been considered; e.g., wireless mesh networks (WMN) in [1], [4], WMN and wireless fidelity (WiFi) in [2], worldwide interoperability for microwave access (WiMAX) in [3] and long term evolution (LTE) in [5]- [7]. However, the competing technologies for the broadband mobile access networks are WiMAX and LTE.…”

This paper proposes a ring-based integrated wireless optical network architecture and an associated protocol that involves Ethernet passive optical network (EPON) and long term evolution (LTE) wireless network. The architecture along with the proposed protocol is instrumental toward the reduction of handover delay. The proposed ring-based EPON architecture facilitates the implementation of the X2 interface for LTE network by enabling the optical network units of the EPON backhaul to directly communicate with each other. The work further discusses about an open access network architecture where a single EPON can be used by multiple mobile service providers without compromising information security. Extensive simulations have been carried out to evaluate the performance of the proposed network. An analytical model has been introduced to calculate the queuing delay experienced by the X2 interface. The model has been validated with the simulations results. Index Terms-EPON, handover, LTE, mobile backhauling, open access, ring topology, RPR, token ring, wireless optical integrated network, X2.

“…Much research has been targeted toward wireless distribution over passive optical networks (PONs) and various wireless standards including 3G, 3,4 LTE-A, 5 WiFi, [6][7][8] WiMAX, [7][8][9][10][11][12][13][14][15] and UWB [16][17][18][19] have been demonstrated overlaying on PON infrastructure. In addition to these wireless standards, a significant amount of work has also been targeted toward millimeter-wave (mm-wave) wireless signals' distribution.…”

Abstract. We present a review of physical networking options and enabling system technologies for efficient unification of optical and wireless access backhaul infrastructure. Different physical layer integration architectures are reviewed in conjunction with the possible wireless signal transport schemes. We also review some of our research work as one possible physical layer integration technique using RF-overlay passive optical network incorporating an optical tandem single sideband (OTSSB) modulation scheme for simultaneous transport of wired and wireless signals.
