“…Ongoing figures gave [37] foresee that there will be up to 70 million little cells, including FBSs, sent by 2017. Their interest has driven some to foresee that in the following 10-multiyear time allotment the quantity of BS including SBSs will surpass the quantity of mobile phone endorsers [38]. It is consequently certain that there is a need to address the vitality productivity of the SBS, especially outfitted with various heterogeneous femtocell, as conceivably tremendous systems of little cells are conveyed.…”

The usage of the network for cellular and Ad-HoC has becoming density due to limitations of capacity, coverage, and Quality of Service (QoS). We introduce the heterogeneous Ad-HoC wireless network for the increase of the coverage and QoS to satisfy the end-users. The proposed research work proposes Heterogeneous Real-Time Transport Protocol (HRTP) and Real-Time Transport Control Protocol (H-RTCP) which utilizes different data formats and standards. For successful packet delivery ration between sources and destinations, the combined HTRP and HRTCP are most close to IEEE 802.11 wireless mesh network. The combined routing protocol and routing algorithm are provided better Packet Delivery Ration (PDR), minimum Jitters, good end-to-end delay, and high throughput. The combined proposed heterogeneous network solves the problems of the number of packets sending over longer distances with different paths and increases the network capacity and converges. The designed heterogeneous network is validated by using the NS2 simulation environment and the obtained results are outperforming when compared with LTE and Wi-Fi technologies. The simulated results are shows that, there is an improvement of 23%, 45%, 12% and 78% in throughput, end-to-end delay, efficiency, and Jitter respectively.

“…Commercial baseband solutions (modems) are also used to deploy measurement campaigns of specific end scenarios. For instance, in , performance measurements are presented for an LTE‐frequency division duplexing (FDD) femtocell system, where an uplink (UL) antenna selection technique (at RF‐level) is used to combat interference from neighbouring macrocells. The testbed is fully based on COTS and features a 10 MHz BW, utilising a real‐time multi‐channel emulator to achieve a scenario with UE mobility.…”

Interference is a major obstacle in radio communications, especially when opportunistic frequency reuse is an inherent requirement for maximizing spectral efficiency in heterogeneous networks. A typical example is encountered in cellular communications where macro cell-edge users receive interference from small cell transmissions that use the same radio frequency band. Innovating interference management algorithms are employed towards this end, which due to their interdependencies with numerous parameters of the target operating scenario and various low-level implementation aspects, need to be prototyped in real-time signal processing platforms in order to be credibly verified. In this paper, we present the development and experimental validation of a macro/femto cell coexistence scenario in close to reallife conditions. The inclusion of an agile interference management scheme increased the signal processing complexity at the physical layer. This overhead was appropriately addressed by engaging advanced parallel processing techniques, optimizations of the arithmetic operations and intelligent reuse of logic and memory resources in the FPGA-based baseband processing architecture.

“…In addition, there are setups that use COTS end-products that include the baseband modems as well, allowing a full real-time operation of the system. For instance, the authors in [9] analyse the performance gains of an uplink antenna selection technique in a LTE-FDD femtocell system, where a channel emulator provides mobility conditions. Similarly, in [10] it is measured and modelled the level of interference caused by indoor LTE-based femtocells through an exhaustive measurement campaign, including UE mobility and a wide range of different femto-BS locations.…”

This paper presents the experimental evaluation of an interference- mitigation scheme tailored for heterogeneous multi-cell LTE-based systems. The real-time FPGA-based system implementation was evaluated under realistic operating conditions using the GEDOMIS® testbed. An intensive measurement campaign was conducted to assess the performance-gains of the proposed scheme, considering mobile channels and various levels of noise and interference.Peer ReviewedPostprint (published version
