Cross-Layer MANET Routing Algorithm Based on Radio Link Stability

摘要

Routing is one of the critical functions in a Mobile Ad Hoc Network (MANET). It enables unreachable mobile nodes to communicate via intermediate nodes. The lack of fixed coordination in MANET compels mobiles to cooperate in order to implement routing, and this cooperation needs simple and robust metrics to indicate which routes are best. The challenge of MANET routing is that node mobility creates rapidly varying links in terms of bandwidth and interference. This paper introduces radio link stability and shows how cross-layer cooperation leads to higher throughput and lower delays by avoidance of unstable links.
