As a result of highly mobility nodes in VANETs, Ad hoc routing protocols
are applied. When a source node demands to transfer data to a destination, it sends
an RREQ (route request) message by flooding into the network, and every node in
the transmission range is taking part to forward this packet. After reception of the
RREQ message by the destination node or by an intermediate node with a valid
route, that node sends back an RREP (route reply) message. The RREP message is
forwarded by unicasting. Only the nodes involved in the RREQ message route
transmit the RREP message back to the source. If an intermediate node fails while
sending back the RREP message because of a battery run out, a link breakage can
occur, which can cause a packet loss of the RREP message or data packet. When
the RREP message or the data packet gets lost, a new route discovery must be
started. The protocol overhead and thus, the performance can be significantly
affected. This paper proposes two routing protocols called E-AODV and
RE_AODV by enhancing the R-AODV protocol with an energy threshold and a
new value of “minimum residual energy” for battery-powered VANET devices.
Both values can be increasing the network performance due to the battery run out
of the nodes.
Further, it can increase the robustness and lifetime of the network. The
enhancements are implemented in the AODV and R-AODV protocol, and the
models are implemented in NS-2. A SUMO model is built for the traffic simulation,
and “mobility files” are imported into the NS-2 model. First, the three protocols E�AODV, R-AODV, and RE_AODV, are compared to determine the competitor to
AODV. For assumed parameters, the RE_AODV-protocol shows higher routing
overhead than AODV, better performance in packet delivery ratio, throughput,
power consumption, and end-to-end delay.
