Greedy routing algorithm

WebThe routing algorithm is a greedy algorithm with the following rules: If the destination t is inside the cluster C.s/of the source s, then s routes to t directly with its routing table. If the destination t is outside the cluster C.s/of the source s, then s ﬁrst routes the packet toward the landmark closest to t.
