The Internet of Things (IoT) is a very large number of objects, with intensive connections and allows these smart objects to be sensed and controlled remotely across efficient network, which is breathing new capability into anything anywhere in the life. This paper presents an overview of about 4G and 5G with their important features and how will drive IoT in future to build smart cities and sm...

Today 4G mobile systems are evolving to provide IP connectivity for diverse applications and services up to 1Gbps. They are designed to optimize the network performance, improve cost efficiency and facilitate the uptake of mass market IP-based services. Nevertheless, the growing demand and the diverse patterns of mobile traffic place an increasing strain on cellular networks. To cater to the la...

C ellular communication systems are continuing to incorporate advanced signal processing techniques. Third-generation cellular systems are already widely deployed and are being followed by fourth-generation (4G) systems. Since 4G cellular technology development is considered to have concluded in 2011, the attention of the research community is shifting toward what will be the next set of innova...

The surge of the Internet traffic with exabytes of data flowing over operators’ mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G UMTS Long term Evolution (LTE) and even of its advanced version LTE-A is evident, considering that the traffic will be extremely heterogeneous in the near future and ranging fr...

Analog optical fronthaul for 5G network architectures is currently being promoted as a bandwidthand energy-efficient technology that can sustain the data-rate, latency and energy requirements of the emerging 5G era. This paper deals with a new optical fronthaul architecture that can effectively synergize optical transceiver, optical add/drop multiplexer and optical beamforming integrated photon...

There is a surge in the amount of mobile data traffic due to the growing popularity of smartphones and tablets and the increasing use of diversified applications that use pictures and movie files. The amount of mobile data traffic is expected to continue increasing with the rise of the Internet of Things (IoT) era, due to a huge increase in the number of telecommunication devices and technologi...

The fifth generation (5G) of mobile broadband shall be a far more complex system compared to earlier generations due to advancements in radio and network technology, increased densification and heterogeneity of network and user equipment, larger number of operating bands, as well as more stringent performance requirement. To cope with the increased complexity of the Radio Resources Management (...
