We propose to strongly reduce the usage of Neighbor Discovery in WSN by ignoring the global IPv6 prefix inside the WSN. The IPv6 prefix will be added (resp. removed) by the Border Router during the header decompression (resp. compression). This proposal has three main advantages: (i) reduce the number of exchanges inside the WSN, (ii) reduce the time needed by a sensor node to join the WSN (this is important when sensors are moving inside the WSN) and finally (iii) simplify multi-homing management. This document also studies the impact of this proposal on different architectures (star, mesh, route over) with LOWPAN_IPHC Encoding Format.
