Due to highly dynamic nature of Mobile ad hoc networks (MANET), predictability and design of efficient protocols and methodology to handle congestion proves to be a tedious task. Since issues and architecture of mobile ad hoc networks are very much different from their counterparts, so are its congestion control strategies due to frequent changes in network’s topology. A noted congestion control mechanism is to notify source for the congestion in the network so that either it may pacify the transmission rate or look for an alternative option. It must be noted down that all the existing methodologies are capable to tell the source about the congestion problem as they use TCP. But in case of MANET, the packet losses due to link failure (due to its dynamic nature) are misinterpreted as packet losses due to congestion, and in the snapshot of a timeout, backing-off its RTO. This results in needless reduction of transmission speed due to which throughput of the whole network degrades. In this paper we implemented hierarchical tree alternative path algorithm for congestion control in Fish-eye state routing algorithm , Order-One Manet Routing Protocol (OOMRP)and novel energy efficient cluster based protocol for highly dense MANET. The comparative results shows that congestion control is very good in proposed cluster based protocol. The throughput is high and packet loss is less and finally energy is saved.
