This paper focuses on providing effective End-To-End (E2E) communications for critical monitoring applications through Wireless Sensor Networks. In particular, the case of frequent disconnection and reconnection has been analyzed, deriving effective routing strategies to cope with this problem. Basing on a recent IETF draft scheme, namely RPL, capable of accommodating several practical situations, a novel approach, called eN Route (NR), has been proposed. In particular, it relies on a two tier network architecture with a hybrid tree-mesh topology, which can be locally rearranged depending on link failures, mainly due to mobility. This is done in a completely distributed way by maintaining a specific neighbor table built only by sniffing data messages to not increase the signaling overhead.
