摘要：VDTN was proposed as a disrupting network
which is established on the paradigm of the delay-tolerant
network. VDTN uses vehicular nodes to convey messages as, it
permits sparse opportunistic network connectivity, which is
considered by the low node density where the vehicular traffic is
sporadic, and no end-to-end paths exist between nodes. The
message bundle is directed from the sender to the receiver node
based on the routing protocol decision. While Routing protocols
take decisions based on different metrics like Time to live,
Location, Remaining Buffer Size, meeting probability, etc. In this
paper, a routing protocol named DesCom is proposed for
Vehicular Delay-Tolerant Network under a highly suppressed
and sparse environment. DesCom takes the decision based on
Message TTL, Transmission rate, and Estimation time.
Estimation time is calculated in our previous work. The protocol
defines whether to direct the message to the requested node or
search the other more suitable node to carry that data bundles.
After compiling multiple simulations with different numbers of
vehicles and comparing DesCom with other routing protocols it
is concluded that DesCom has the least buffer time with low
latency along with good delivery probability.
