An analysis of the optimum interactive mode of control message for ad hoc mobile networks

The wireless ad-hoc network is self-organizing. rapidly deployable and without fixed infrastructure. The hosts in ad-hoc networks communicate with each other over a wireless channel without any centralized control. The basic problem is to obtain a distributed routing scheme so that any mobile host can transmit/receive data from any other host in the network. As we know, in terms of the way in which nodes obtain information, routing protocols for ad-hoc networks have been classified as table-driven and on-demand. In table-driven routing protocols, the interactive mode of the control message has a great effect on network performance. In this paper, a novel concept of "different interactive mode for different scale of network" is presented. The network performance is optimized by using appropriate periodical or nonperiodical interactive mode based on the scale of the network. A different interactive mode is given for different scales of the network by theoretical analysis and algorithm simulation. The simulation result is of great practicability.
