Mobile ad hoc networks (MANETs) consist of mobile devices that communicate with each other without a predefined fixed infrastructure. Using of MANETs provides significant benefits in emergencies thanks to this feature. Various malfunctions such as end to end delay, bandwidth congestion and, reduction in the packet transmission ratio occur in data transmissions due to dynamic and variable connections in emergency and rescue scenarios. In this study, Emergency Ad hoc On-Demand Distance Vector (EAODV) protocol, giving priority to TCP packets, was developed by modifying the queue structure of the AODV protocol. It is aimed transmitting data within less end to end delay time along with increasing packet transmission ratio and throughput, through E-AODV. The performance of proposed protocol was investigated on two different scenarios in a simulation environment and compared with similar studies in literature. E-AODV gave more successful results in terms of the packet delivery ratio, end to end delay and, throughput for the both scenarios.
