A new hybrid routing algorithm: GHR (Group Hierarchical Routing)

Ad-hoc network is becoming more important in various areas for wireless communications. In the network, routing algorithms have a great influence on the communication performance. To minimize network overheads, this paper proposes a hybrid routing algorithm, Group Hierarchical Routing (GHR), which is a combination of proactive and reactive routing methods. The comparison with other hybrid routing methods shows that GHR has less communication complexities in route discovery and maintenance.
