A Survey on Performance Improvement in Power Heterogeneous MANETs

Abstract

In MANETs, network may consist of devices with heterogeneous characteristics in terms of transmission power, energy, capacity etc. especially in VANETs. In such heterogeneous networks, 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. This paper highlights methods to improve the routing performance of power heterogeneous MANETs by efficiently exploiting the advantages and avoiding the disadvantages of high-power nodes.
