a solution to memory fragmentation?

[thorwald]

In [1] they mention that contiki-os has a compacting memory allocator , which solve the fragmentation issue(at the cost of some latency). contiki-os is open-source.

In a previous thread, damien mentioned the complexity of making such allocator. Maybe taking on from contiki will work?

[thorwald]

here's the link to the source(from contiki):

No, taking it from contiki doesn't help. Compacting memory allocator is a trivial algorithm. It's adapting it for particular requirements and building the whole system ("world") where this compaction happens transparently is non-trivial. Contiki in particular doesn't do that.
