Mesh networks are becoming ubiquitous in both wireless access and wide-area overlay networks. The Internet of Things (IoT), the tagging and virtual representation of everyday appliances as a smart network, is the ultimate embodiment of a global mesh network. Such a vision is starting to be realized through the development and integration of various sensor networks, wireless local and metro networks, device-to-device (D2D) networks, as well as satellite networks.
Whether they are built of wireless links or overlay tunnels, mesh networks are often subject to harsh packet losses.
The ITU-T G.hn family of home network standards, for instance, specifies local mesh networks built over power lines, phone lines and coaxial cables. While coaxial segments benefit from higher rates, noisy power lines pose particular technical challenges and support limited rates. Wireless sensor networks such as monitoring networks are often vulnerable to weather conditions and geographical layout, also leading to high packet losses.
To counter packet losses, mesh networks resort to frequent packet retransmissions. The resulting large energy consumption represent a fundamental limitation in network planning, not only for wireless sensor networks but also in WiFi meshes.
Our technology reduces signaling by simplifying broadcasting, dissemination, and retransmission operations. Furthermore, it minimizes the required number of transmissions across the network in dynamic loss and connectivity conditions. Our algorithms are shown to decrease delay in D2D networks by 3.6x and to decrease overall energy consumption in wireless mesh networks by a factor of 3.9x.
By facilitating D2D cooperative networks, our technology creates new opportunities for file sharing and gaming applications.
Our partners at Steinwurf provide optimized mesh networking tools.
