Abstract
The paper proposes a new blockchain-based network architecture for 5G network functions virtualization. By using a combination of AI and blockchain technologies, proposed system provides flexible network deployment, interoperability between different mobile network operators and effective management of radio resources. Experimental testbed of the proposed system has been implemented by using cloud and edge computing infrastructure and software defined radio peripheral NI USRP 2900. Simulation results of the network slicing and radio resource management shows that proposed system is able to double the capacity of the physical network infrastructure, while ensuring the target quality of service for all users.
Highlights
With the advent of 5G trend, mobile networks became even more heterogeneous in terms of transmission range, data rates, capacity and energy efficiency. 5G essentially became a buzzword for any radio access technology, which has emerged after 3GPP Release 10, such as small cells, device-to-device communications, massive MIMO antenna arrays, new modulation waveforms, LTE-unlicensed, narrowband-IoT, mmWaves and many others [1]
Since all end-to-end services in 5G are created from virtualized service functions, there are key differences in functionality that results in the new paradigm Network Slicing as a Service according to the following rules: 1. Service orchestration and slice management need to be application aware
We have proposed a novel blockchainbased architecture for 5G network function virtualization
Summary
With the advent of 5G trend, mobile networks became even more heterogeneous in terms of transmission range, data rates, capacity and energy efficiency. 5G essentially became a buzzword for any radio access technology, which has emerged after 3GPP Release 10, such as small cells, device-to-device communications, massive MIMO (multiple input multiple output) antenna arrays, new modulation waveforms, LTE-unlicensed, narrowband-IoT, mmWaves and many others [1]. 5G essentially became a buzzword for any radio access technology, which has emerged after 3GPP Release 10, such as small cells, device-to-device communications, massive MIMO (multiple input multiple output) antenna arrays, new modulation waveforms, LTE-unlicensed, narrowband-IoT, mmWaves and many others [1]. This essentially introduced a large number of additional degrees of freedom for the end users in terms of connectivity options. These additional degrees of freedom substantially increase the complexity of network optimization, management and maintenance for the operators.
