Routing with virtual coordinates in mobile sensor networks

The realization of smart cities relies on the availability of large amount of data about occurring phenomena/events that can be guaranteed by very large deployments of Wireless Sensor Networks (WSN). This poses a great challenge to the scalability of current routing protocols for WSN due to the size and density of the network and the presence of mobile sensors.We tackle this problem by proposing a solution based on virtual coordinate systems combined with mechanisms that renew the virtual coordinates and suitable routing schemes. The simulation results show that this approach is actually suited to this context and that it guarantees high delivery rate and low path length.
