Modified Energy Efficient Quality of Service Provisioning based on Energy and Preemption for Mobile Ad hoc Networks

  • Amit Garg et al.


Mobile Ad-hoc Networks (MANETs) consist of mobile nodes and these participating nodes
may communicate with each other without any physical infrastructure. The neighboring nodes
may communicate directly within their transmission range and through multi-hop if they are out
of their transmission range. The MANET is dynamic in nature and participating nodes are very
prone to failure because of consumable power supply. Therefore, the implementation of Quality
of Service (QoS) provisioning is one of the challenging tasks in MANET. In the proposed scheme,
to reduce the interruption in data transfer from one node to another, the energy of each node is
monitored and identifies in case of available battery power is low or the rate of energy
consumption is very high during the transmission. The simulation study has been done on the
proposed scheme by taken certain parameters into consideration for evaluating packet delivery
ratio and throughput. It has been observed that the proposed scheme produces better results
comparatively in terms of packet delivery ratio and throughput with a fixed number of
participating nodes when compared with existing AODV protocol. Further, the performance of
the same scheme can be evaluated for highly dynamic networks and on certain other parameters.
