This method USES intermediate nodes' location information to create undirected graph at destination node, and USES Breath-First Search (BFS) algorithm to find another disjointpath.
And in order to select stable multiple routes similar with the shortest path, RNDMRA USES similarity factor to select similar stable node-disjoint multipath routes.
To solve the common-link and common-node problem, disjoint multi-path routing (DMPR) is employed where sensors send data to the sink through link-disjoint or node-disjointpath.
