Modeling and evaluation of location-based forwarding in vehicular networks

Location-based forwarding plays an important role in vehicular networks to dissem- inate messages in a certain region beyond the immediate transmission range of the originator. In this chapter, we introduce an analytical performance model that cap- tures the behaviour of location-based forwarding in great detail. We consider a one- dimensional scenario with exponentially distributed inter-node distances and a realis- tic radio propagation model. The model captures the complex correlations between consecutive hops and gives valuable insights regarding the forwarding process. The overall performance measures derived reveal the characteristic behaviour of location- based forwarding. For example, the end-to-end delay has a multi-modal nature, with each mode corresponding to a number of hops used to reach the destination
