Next Generation Communication Group:

Objective:

Over the past few decades, Communication Technology has grown by leaps and bounds. Regardless to this, there is significant scope for enrichment in terms of economics, effectiveness, efficiency and performance of communication technology. The research focus of this Group is to develop intelligent and cognitive communication models and protocols, which aid the evolving applications to Smart Cities, Green Communications and Internet of Things (IoT). The research is focused on creating communication models and protocols which improve high data rates, heterogeneity, autonomy and scalability of communication technology. The research in the next communication group encompasses the following focus areas:

  • Physical layer aspects
  • New medium layer aspects
  • Network layer protocols for wide area applications
  • Heterogeneous Wireless Network Communications
  • Deterministic Propagation Modelling

Wireless communications and wireless networks are the backbone technologies for the evolving smart city technologies. Our group is so foundational for solving the challenges of the smart city technologies. We are focusing on scalability, heterogeneous protocols support, handovers etc. to assure the success of smart city technologies. This group is also actively doing research in Internet of Things (IoT) and Machine to Machine (M2M) addressing some of the research challenges in Vehicle-to-Vehicle communications, Wireless ad-hoc networks for precision agriculture and smart building. The research produced by the Next-Gen Communications Group will have a significant impact on the general society, Government of India initiatives such as Smart Cities and companies working on novel communication models and networks for future generations.

Despite the multi-fold growth of Wired and Wireless Communications in the past few decades, there is a tremendous scope to improve the existing communication models to make them more economical, efficient and high performance systems for futuristic requirements. This group has been started with a vision of developing cognitive and intelligent communication models or protocols aiding the evolving applications like Smart Cities, Smart Transportation, Green Communications and Internet of Things (IoT). The primary research interests of this group are to design communication models with features of resiliency, high data rates, heterogeneity, autonomous and scalable systems. Currently this group focus on developing on the following aspects: Physical layer aspects; New Medium Access layer and Network layer protocols for wide area applications; theoretical, simulation and experimental models for adaptive, resource efficient and greener communications; heterogeneous wireless network communication, physical Layer design aspects of tiny hardware targeting IoT sensing applications, microwave, antennas, etc. The outcomes of this research group have significant short and long term societal benefits for Government of India (GoI) initiatives like Smart Cities, connected society, and also the requirements of other private industries and researchers targeting for novel communication models for evolving applications of next generation communication and networks. Further, with the enormous requirement for high speed large data transfer, researchers are looking into millimeter-wave (60 GHz) communication systems. At this high frequency range it is therefore extremely important to model the propagation channel accurately (using deterministic propagation modeling using ray tracing and high-frequency asymptotic techniques) so that multiple antennas may be accurately fed with correct amplitude and phase to achieve precise beamforming and thereby high data rate.
