In MANETS, networks may consist of devices with heterogeneous characteristics in terms of transmission power, energy, capacity, radio, etc. In such heterogeneous network, nodes are likely to transmit at different power levels, thereby causing communication links of varying range. This causes link asymmetry problem. Also, due to interference raised by high power nodes, the throughput of such networks will be severely affected. Literature survey of current works, suggest ways to only detect the unidirectional links and to avoid transmissions through such links. They do not consider the benefits of high-power nodes.
