Abstract: It is difficult for delay tolerant Mobile Ad-Hoc Networks (MANETs) to render the end-to-end paths from source to the destination where there is no proper connectivity. Opportunistic routing overcomes the deficiencies of conventional MANET routing, and the proposed algorithm works based on quadrant-based look-ahead approach, which is highly efficient in managing the traffic uniformly, conserving energy, and increasing the lifetime of nodes as well as improving the route network stability. The proposed method aimed at reducing the amount of time that packet spends in the buffers. Simulation studies reveal that the proposed novel routing approach outperforms the existing methods.


Keywords: opportunistic routing; MANETs; stability; connectivity; delay tolerance; mobile ad-hoc networks; quadrant-based look-ahead; network traffic management; energy conservation; network lifetime; simulation.
