Enhancing connectivity based on the tresholds in mobile Ad-Hoc networks

초록

In general mobile nodes in mobile Ad-hoc networks have a limited power capacity. Therefore power management is an important issue. Some protocols are proposed considering node power consumption, such as MTPR, MBCR, MMBCR, CMMBCR. But they have no measures on link breakdown from power exhaustion of relay nodes. We propose three algorithms to prevent link breakdown and to extend the connectivity of the routes in mobile Ad-hoc networks. In these ways, the lifetime of routing nodes can be extended and the link connectivity can be enhanced. Moreover the delay due to reacquisition of the route is reduced and the throughput degradation from link breakdown is avoided.
