SMART:Scalable Mobility Adaptive Routing Techniques for Heterogeneous Mobile Networks
Tomohiko Yagyu, Masahiro Jibiki, Kenichi Yoshida · 2007
Most wireless networks consist of heterogeneous nodes with diverse characteristics. These heterogeneous nodes have various moving characteristics such as speed and direction. Since conventional wireless routing schemes are designed for networks with homogeneous mobility, they have to cope with the routing difficulties between heterogeneous nodes by careful tuning of routing parameters. Because optimally tuning to such parameters is difficult, this tuning tends to result in higher control overhead and to degrade communication quality, e.g., lower packet reachability and higher packet delay. This paper proposes efficient extensions of a proactive routing protocol to achieve sufficient communication quality in heterogeneous mobile networks. Simulation results reveal that the proposed scheme can achieve higher packet reachability and lower delay with low control overhead compared with existing routing schemes.
