Abstract
In order to achieve the capacity and geographic scope required by IoT applications, service providers should explore mutually-beneficial modes of collaboration such as through cooperative packet forwarding by IoT nodes and cooperative gatewaying through fixed backhauls. To promote such resource pooling while minimizing negative impact on collaborating providers, we developed a transport-layer approach that combines multipath techniques with less-than-best effort (LBE) congestion control methods to enable IoT nodes to opportunistically scavenge for idle bandwidth across multiple paths. Initial tests using TCP-LP and LEDBAT congestion control algorithms on scavenging secondary flows show that this desired functionality can be achieved, while our use of standard TCP congestion control on primary flows ensures that IoT nodes are guaranteed at least one flow that can compete for fair share of the network capacity.
