A new routing scheme based on the terminal mobility in mobile ad-hoc networks

A mobile ad-hoc network is composed of only mobile nodes, which are distributed dynamically, without any wired backbone or centralized entities. Each terminal in the mobile ad-hoc network also has the role of the router, but the frequent changes of the terminal positions induce a waste of time, energy and computing power for updating the routing table with the paging, and also may provoke a call dropping. To overcome this problem, we propose a new routing scheme based on the terminal mobility in mobile ad-hoc networks. In the proposed scheme, terminals are classified into low-mobility terminals and high-mobility terminals. To prevent the frequent update of the routing table, only the low-mobility terminal can be the routing terminal in the proposed scheme. The performances of the proposed scheme and conventional scheme are simulated. The numerical results show that the mean call dropping time in the proposed scheme are much lower than that in the other conventional schemes
