Abstract:
AFOD (Adaptive Fidelity On-Demand) protocol has taken advancement over AODV and DSDV protocol targeting multimedia applications where the QoS parameter is considered for bandwidth, delay and node lifetime. The energy consumption during disasters is monitored carefully as the communication
modules utilize a limited power supply for which AFOD protocol discovers the path from the source to the destination while the topology of the nodes changes beyond a limit reducing the endto- end delay else the previously determined least cost paths are used to communicate. In this paper it is explained the capability of AFOD involved in altering the transmitted power of the source node dynamically according to the distance of its NEXT HOP, thereby utilizing only the power required to maintain the acceptable signal-to-noise ratio at the receiver or the next hop. The simulation results are encouraging as the AFOD clearly outperforms AODV and DSDV by reducing the End-To-End delay by 80{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} and 40{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} respectively during the topology of nodes not changing rapidly making the unique path discovery technique of AFOD dominating over other protocols.
