To reformulate my problem I will take an example : A sensor have the choice between two parents to connect itself to a collection data path. By default it chooses the bad parent in the sense that this one reads very different datas. (assuming that a good parent is a sensor that read similar datas)
So what I would like to do is that when the sensor overhear (snoop) a data message from the good potential parent, it indicates to the Ctp mechanism that it should consider this sensor as a better parent than the current one. It would be like not only taking into consideration ETX but this global behavior too. Is there any way to perform that ? 2009/4/28 Rémi Villé <[email protected]> > In fact I would like to have a routing corresponding to my network layer, > in the 4-bit wireless link estimation, put the compare bit at 1 when I > receive a similar data from a neighbor... > > I don't know what interface, command or event to use, and I have no example > to do this sort of thing. > > 2009/4/27 Rémi Villé <[email protected]> > > Hi, >> >> I'm new with TinyOS, I used Collection with the MultihopOscilloscope >> tutorial, I have seen some TEP on Collection, Ctp and LEEP. >> I have understood Collection performs less hop data paths and use ETX to >> use a link instead of an other one regarding to the ratio of received >> messages and lost ones. >> >> I would like to have a customized Collection which takes into >> consideration sensed data, i.e. not just good quality link but e.g. if a >> neighbor node senses data close than current one (for aggregation). >> >> What should I use in TinyOS features to perform that, is there any >> component to do it simply, or should I modify Ctp or LEEP components ? >> >> Thanks in advance, >> >> Rémi >> > >
