Title
(EN) Method, apparatus, and protocol for improving performance in a wireless network
Abstract
(EN)

A wireless network protocol (CORE) and related methods, systems, and circuits are disclosed that are capable of enhancing network performance. The protocol uses random linear network coding (RLNC) for intra-session coding in the network, while allowing nodes in the network to set up inter-session coding regions where flows intersect. Within the inter-session coding regions, combinations of coded packets associated with different unicast sessions are permitted. However, packets associated with multiple different unicast sessions are not allowed to be transmitted outside of the coding regions.
