CIVIC Geographic Routing Protocol


A wireless geographic routing technique used in vehicular ad-hoc network, precision agriculture and smart home.


CIVIC is a quick reaction and low resource consumption geographic protocol for inter-node (i.e. inter-vehicle) message transmissions. The protocol forwards the network packet to the progress direction by using the greedy minimum-angle techniques. In this forwarding process, the protocol takes in account the reliability and resource awareness of the next-hop candidates by using the parameters of speed, direction, and remaining energy and memory. These allow the protocol greatly reducing the number of involved next-hop candidates, thus it can shorten the reaction delay and reduce the resource consumption.
