Analysis of the impact of hello protocol parameters over a wireless network self-organization

Abstract

The neighborhood discovery and its maintenance are very important in wireless networks for any applications, especially for routing and every self-* algorithm. Neighbor nodes are usually discovered thanks to the use of the HELLO protocol. This makes this HELLO protocol very important for wireless networks especially for self-organizing the network. Most of layer-3 protocols assume an ideal MAC layer. In such a case, HELLO protocol parameters have no impact over the self-organization. But this is not the case when considering realistic MAC and physical layers. In this paper, we investigate the impact of the parameters of such a protocol over a self-organization structure when considering realistic a MAC layer. We analyze theoretically and by simulations, the joint effect of the HELLO protocol parameters and of the MAC layer characteristics over several network self-organizations.
