Improving link metrics - -The sheer measurement of the OGM delivery ratio is -a poor metric for link quality evaluation. -It is not able to distinguish fast links from slow ones, -it is not able to tell congested links apart from -unused ones, it is not able to distinguish point-to-point -links from broadcast ones. -Improving the link evaluation metrics without becoming -dependent from the specific link-level technology is however -a challenge. Exploring the role of delay, delay jitters, information -coming from the data plane (for instance in 802.11 data packets are -sent at different link speeds depending on the actual destination -and not at the base speed used for broadcast) can yield results -leading to improved metrics. - -h3. Improving multi-radio strategy - -In presence of multiple (wireless and wired) interfaces -the present strategies for interface selection in Batman are -based on simple and non-general heuristics, with the -consequence that very often sub-optimal decisions are taken. -To improve these strategies the following fundamental points need -attention and solutions: -a) Capability to differentiate between different MAC/PHY layers -(e.g., a reliable 1Gbit/s optical link from WiFi, or also a -reliable point-to-point WiFi bridge from a generic multi-point -WiFi interface). -b) Metrics and algorithms for iteratively improving the topology -based on the above information. - -h3. Improving Broadcast communications - -Some applications, specially related to network management like -????, or to services publish/subscribe models, require efficient -and reliable broadcast/multicast (IP layer) communications, which -are however always mapped onto layer 2 broadcast packets. -Presently batman transmits these packets 3 times, with a large overhead -and still no guarantee of delivery. -Many solutions can be studied, starting from intelligent re-broadcast -to multiple-unicast flooding. - -h3.
