Cross layer design of energy efficient multipath routing protocol using adjustable sleeping window in manets

Mobile ad-hoc networks (MANETs) have gained great importance in today´s commercial communication markets. These networks consist of several nodes that can communicate with each other without any fixed infrastructure. The nodes in these networks are highly dynamic and they are also battery powered. Hence energy efficiency is one of the important factor that has to be considered in MANETs. In this paper, we have designed an energy efficient multipath routing protocol using adjustable sleeping window (EMRAS) by implementing two algorithms - power and delay aware multipath routing protocol (PDMRP) and slow start exponential and liner algorithm (STELA) using cross layer design. STELA algorithm helps to improve the energy efficiency of the network by adjusting the sleeping window when there are no network activities. When there is any network activity, PDMRP helps to select the path which is energy efficient and also shortest. Simulation results show that EMRAS protocol has improved the overall residual energy and reduced the total energy consumption without degrading the QoS parameters.
