In Content-Based Mobile Ad-hoc NETworks (CBMANETs), random linear Network Coding (NC) can be used to efficiently and reliably disseminate large files under intermittent connectivity. Conventional NC involves unrestricted re-encoding at intermediate nodes, and consequently is vulnerable to pollution attacks. To avoid pollution attacks, the most computationally and energy-efficient approach is to restrict the encoding at the source. However, source restricted encoding generally reduces the robustness of the code in the face of errors, losses and mobility induced intermittence.
