An Area Content Distribution Scheme Based on Local Response Service for Vehicular Ad Hoc Networks
Disseminating content to a specific geographical area and keeping for a period of time for high dynamic Vehicular ad hoc network( VANET) is a challenge task. A local response service( LRS) based area content distribution scheme is proposed. The scheme codes the distributing content with random linear network coding and caches it to the mobile vehicles within the service area randomly so that all the requests from the nodes located in the service area can be serviced by any surrounding neighbors. NS-3 simulation results show that the scheme can reduce the distribution delay effectively and consequentially improve the delivery ratio of the system.
