Comparisons of Inter-Domain Routing Schemes for Heterogeneous Ad Hoc Networks

— In this paper, we propose three interdomain routing schemes for communications between different ad-hoc groups (subnets), namely the implicit foreign degree based (IFD), the explicit locally optimal (ELO) and the explicit limited scope (ELS) protocols. The IFD scheme mandates that only local nodes can hear a certain number of foreign nodes are qualified to be chosen as the gateways for forwarding interdomain route requests. The ELO and ELS schemes choose the node with the highest score within its local scope as the gateway, but they differ in terms of routing protocols. The ELO uses reactive routing protocol while the ELS scheme uses a hybrid approach i.e., a proactive routing scheme within the scope and reactive scheme outside the scope. In our paper, we compared the performance between these different schemes that we proposed. Our simulation studies reveal that the explicit schemes can achieve high packet delivery ratio and good average end-to-end delay at a lower overhead cost c...
