[Tinyos-help] Alternative to Dissemination Protocol??

[Christian Hermann]

Hallo,
does anybody know a good multihop-routing alternative to the
dissemination, protocol? My tests with the dissemination were
quite disatisfying. It needs to long do disseminate a msg to
all nodes (several seconds). And in my case I would like to
have the possibility to send different messages to different
nodes nearly on-time of request.
Thanks
Christian
