In Mobile Ad hoc NETworks (MANETs), the freedom in mobility of nodes lead to rapid link breakages causing simultaneous route discoveries and variable topology shifts. Flooding is the common solution opted for finding routes. Despite its simplicity, flooding results in redundant rebroadcasts, collision and contention problems collectively referred as the Broadcast Strom Problem, increasing the routing overhead. Apart from the vital role played by the control messages (RREQ, RERR, RREP, and HELLO MESSAGES) and neighbor list table, the routing overhead caused has a considerable higher impact in networks performance.
