RESUMO

The number of applications that relies on wireless sensor networks has grown fast. However those networks are vulnerable to fails and attacks that may disturb or even stop completely important information diffusion through it. In most scenarios, removing or disabling the bad nodes causing those anomalies is simply not possible. The alternative we found to solve this problem was the development of a protocol able to isolate such anomaly regions and build detours around them: the IDEA. To build those detours, the IDEA protocol defines multiple reference path lines that are graphical representations of equations in Cartesian plane. In order to evaluate this proposal of us, we made an implementation of IDEA on ns-2. The simulations we did showed, among other results, that this protocol has a good success rate on building the detours, and that the use of multipath extends the energy of the nodes involved on the detours.
