Cluster-based architecture for three-hop communication in next generation wireless networks - Vol.103(2), Apr - New York Springer 2022 - 293-304p.

Over the last 10 years, there has been an exponential growth of Internet services over cellular and wireless network. This has resulted in multiple wireless networks: macro-cell, micro-cell, femto-cell, legacy networks, etc. co-existing simultaneously. Multihop cellular networks have been well-investigated to support the heterogeneous wireless network scenario. However, this results in a very distributed and a non-optimum distribution of radio resources, leading to sub-optimal throughput of the network. Keeping this in mind, this paper proposes a three-hop heterogeneous wireless network architecture, wherein each hop would be from same network or other networks. Importantly, this paper proposes and provides a detailed analysis of a specific cluster-based architecture: three-hop network. This is the first instance where a three-hop architecture is analyzed. Accordingly, in every cell, three communicating pairs communicate using a given radio resource, but for only 1/3rd the time slot period. This three-hop design enables a frequency reuse ratio of one. A comprehensive performance analysis indicates that the capacity obtained with a three-hop architecture is up to 20% higher than that can be obtained by two-hop architecture and 40% higher than traditional single-hop network. This is an extremely important result. It indicates the improvement that can be obtained in using specific design for multihop-based next generation LTE-advanced network.
