ABSTRACT

This paper proposes a virtual mobile ad-hoc network (VMANET) model that automaticallydivides heterogeneous mobile devices of a MANET into a number of network groups depending onthe communication capacity(data rate) of different network operational models such as IEEE802.11g, IEEE 802.11b, and Frequency Hopping. In addition, it supports a distinct routing protocol for each network group of VMANETs, resulting in running multiple routing protocolsconcurrently on different groups of VMANETs. To reduce the network congestion and improve thenetwork load balance, a default MANET gateway is configured in each VMANET and thesegateways are responsible for integrating the MANET and IP networks. Experiment results showthat the proposed model outperforms the conventional IMANET by significantly increasingthroughput and reducing network congestion and network delay.
