Abstract

Recently, D2D communication is drawing attention as a technology 
capable of reducing an excessive load on a network infrastructure and
increasing network coverage. When using heterogeneous wireless 
communication technologies such as WiFi and Bluetooth, which are 
basically provided to user terminals such as smartphones, the 
connectivity of D2D communication can be further strengthened.
In this paper, we propose a multi-hop communication technique using 
heterogeneous wireless communication technologies.

1.  Introduction

As the amount of mobile traffic generated by user terminals such as 
smartphones, which are widely used in recent years, is rapidly 
increasing, a direct communication between terminals (D2D) technology 
is attracting attention as a technology for preventing excessive load 
on the network infrastructure. In particular, most user terminals such 
as smartphones are basically equipped with various wireless 
communication interfaces such as WiFi and Bluetooth as well as cellular 
interfaces. In an environment in which various wireless communication 
technologies are mixed, a multi-hop communication technology composed 
of heterogeneous links can provide more opportunities for connection 
between user terminals. In fact, it is known that the use of D2D 
communication services such as OpenGarden can increase the message 
delivery rate up to 80% in dense crowd environments such as movie 
theaters and concerts and emergency situations.
When implementing multi-hop networking technologies in the application 
layer, it has the advantage of supporting interworking between wireless
communication technologies that are rapidly developing with the advent
of the Internet of Things era without modifying the operating system. 
Therefore, in this document, we propose a heterogeneous multi-hop 
networking technique in the application layer and discuss 
considerations.
