LQM: A Link Quality Based Multipath Scalable Proactive Routing Protocol for Mobile Ad Hoc Networks

The day by day rising interest in multimedia communication has immensely grown the size of the Mobile Ad hoc Networks. For more than hundred nodes the mobile ad hoc networks are not able to work effectively as these are not scaled properly. Current ad hoc routing architectures are largely based on flat static addressing schemes and need to keep track of each node individually. This leads to a massive overhead problem as the network size grows. Many solutions have been proposed to overcome this problem and the most appropriate solution is to divide the whole network into the groups or hierarchy. This paper aims to propose a Link Quality based Multi-path data forwarding routing protocol, called LQM, which is based on Dynamic Address hierarchical scheme for Mobile Ad hoc Networks. In this work we emphasized on two prime factors - link failure rate and link bandwidth that mainly govern the link quality of network. The performance of LQM has been investigated with the simulation runs across different experimental setups. The results confirm that LQM exhibits better or at least comparable performance with respect to DART and M-DART, the two dynamic address hierarchical scheme based routing protocols in all considered scenarios.
