Multiclass On-demand routing in heterogeneous ad hoc networks

In this article, Ad hoc On-demand Distance Vector (AODV) routing protocol is modified to introduce a multiclass on-demand routing mechanism for ad hoc networks. The proposed protocol supports two distinct traffic classes, realtime traffic and non-realtime traffic. The anticipated protocol also takes into account the heterogeneity of the network while making the routing decisions, i.e. the yielded routes may comprise of dissimilar link layers. These modifications are implemented and evaluated on an actual ad hoc network testbed comprising of eight mobile nodes.
