 Experiments on real-hardware testbeds, have shown that even if the nodes in WSNs are static, the network exhibits high dynamics because of the instability of communication links and the disappearance of some of the nodes due the depletion of their energy and to their failure. New nodes can also be added to the network at any time, which also causes variable network connectivity. Furthermore some of the sensor nodes could be mobile, being worn by humans, carried by animals, or mounted on mobile robots and vehicles.
 == Objectives of ROME ==
-ROME is designed for WSNs characterized by high dynamics, such as node addition, node removal and the mobility of some of the network nodes.
-It has the desirable properties of optimized performance through cross layer design, receiver-based relay selection, asynchronous nodal duty cycles and the ability to deal with connectivity holes in the network topology all aimed to solve the WSNs issues.
+ROME innovation provides the SENSEI architecture with an energy-efficient multi-hop connectivity function for WS&AN islands. Specifically, it is possible to send interest requests to the nodes in the island through a SENSEI gateway, and collect sensed data. The protocol is energy efficient, as it addresses the energy constraints that are typical of devices in WS&AN islands. Each node in the island follows an asynchronous duty cycle (e.g., it is awake the 10% of time, while it is asleep in the remaining 90% of time) so that energy usage is balanced in the network. 
+Besides energy efficiency, the major distinguishing factor of ROME is its ability to rapidly adapt to changing network topologies, ensuring WS&AN connectivity also in presence of nodes mobility and addition/removal.
