A new architecture of integrated cellular and ad hoc networks system in the dead spots was introduced
and the system’s relay-availability probability under this environment was analyzed.Then by combining with the relay-availability probability
build the analytical model of integrated cellular and ad hoc networks system
and based on this model
get the call dropping probability of the traditional cellular system and integrated cellular and ad hoc networks system respectively by mathematical analyzing.Finally
through numerical simulation
compare the two kinds of system’s performance under the environment of dead spots
and analyze the impact of the various parameters on the integrated cellular and ad hoc networks system’s performance.
