GPSR will allow the building of networks that cannot scale using prior routing algorithms for wired and wireless networks. Such classes of networks include:
Sensor networks: potentially mobile, potentially great density, vast numbers of nodes, impoverished per-node resources
Rooftop networks: fixed, dense deployment of vast numbers of nodes
Vehicular networks: mobile, non-power-constrained, widely varying density
Ad-hoc networks: mobile, varying density, no fixed infrastructure
