Dahrwin, a US-based company that develops mesh network solutions, was faced with the challenge of implementing their idea of a cross-platform mesh network solution. The solution was to be built from scratch to meet the needs of different industries, such as V2V communications and for establishing connections in zones with no service. The company needed a strong engineering team specializing in both hardware and firmware development. The challenges included designing and implementing the prototype of a dynamic mesh network solution using Android based mobile phones and utilizing WiFi ad-hoc capability, developing hardware for an efficient mesh network, developing the software protocol powering the dynamic work of the network, ensuring compatibility with different platforms, implementing a faster launch of embedded Linux, and taking into account obstacles, noise and other conditions to ensure the highest quality of the solution.

Dahrwin is a US-based company that specializes in the development of mesh network solutions. This technology eliminates the need for the Internet to connect with people around you as it allows its users to create and join independent wireless networks from a mobile device. The company needed a solution that could be built from scratch to meet the needs of different industries, such as V2V communications and for establishing connections in zones with no service. They required a strong engineering team that specialized in both hardware and firmware development to implement their idea of a cross-platform mesh network solution.

N-iX engineers developed a proprietary communication protocol with adaptive routing, the custom hardware network node running embedded Linux, customized Android firmware with integrated mesh network capabilities, and more. They provided full cycle development of the solution. The team analyzed the client’s requirements and suggested enhancements to the solution to make it more efficient. They designed and implemented a prototype of a dynamic mesh network solution using Android based mobile phones and utilizing WiFi ad-hoc capability. The programmers created demonstration software for Android and iOS, and implemented internet connection (TCP and UDP) tunneling through the mesh they developed. The embedded team developed a custom device, called Dahrwin router, that could connect WiFi networks with different topologies. The engineers selected OpenWRT project and ported it to run on their custom hardware.

• The engineering team successfully implemented all the client’s tasks and delivered an innovative mesh network solution comprising wide functionality. The solution included a hardware independent cross-platform mesh network solution (Android, iOS, Linux), a proprietary communication protocol with adaptive routing, a custom developed hardware network node running embedded Linux designed for bridging networks with different topology, customized Android firmware with integrated Dahrwin mesh network capabilities, internet connection (TCP, UDP) tunneling and sharing over mesh network, mobile messenger applications working via mesh network for iOS and Android, minimum administration of the network, no need for a lot of configuration, and providing various types of connection, high network reliability.
