Abstract
The existing routing protocols in mobile ad hoc networks assume that all nodes have the same transmission range. In other words, the mobile ad hoc network has only symmetric links. However, since nodes consume battery power independently according to their computing and communication load, there exist asymmetric links, which means that node A is within node B's transmission range, but not vice versa. This paper present two protocols that accomodate asymmetric links: link-level and end-to-end Approaches. The link-level approach can be applied to any routing protocols by utilizing GPS (Global Positioning System) location information of nodes at link level. On the other hand, the end-to-end approach does not need GPS devices and employs dual paths between source and destination. Simulation results reveal that these protocols cope well with ad hoc network having asymmetric wireless links under the presence of mobility.
