As a reference other MIBs can be used. Wiht Using snmpb you can load them (located at /usr/share/apps/snmpb/mib) and modify the fields according to your needs. The following example is a very simple approximation to what we want to monitor from motes. Note that in some cases, instead of single values we want to deal with arrays as a mote can have more than one neighbor.
