In MANETs (Mobile Ad hoc NETworks), network may consist of devices with multiple characteristics in terms of transmission power, energy, capacity etc. Especially in MANETs, network may consist of devices with multiple; nodes are likely to transmit at different power levels, thereby causing conversation links varying. This causes link asymmetry problem. The link asymmetry problem can be solved by using a cross layer approach without considering the benefits from high power nodes and collision may be avoided using carrier sensing. The presence of high power nodes in MANETs has its own advantages like coverage area and reduction in transmission delay. At the same time, disadvantages like interference and noise. The existing cross layer approach does not address the above problem.
