|Abstract:||Applications like Twitter which use chat-like short
messaging systems (SMS) have been widely used in public,
political, military, emergency, humanitarian and other fields.
Such applications usually involve servers (controllers) which
control and forward messages from a sending client to a receiving
client. The use of mobile wireless networks for such messaging
systems has been increasing at a fast pace. To cope with this
increase, there need to be efficient communication protocols and
algorithms. To design such protocols and algorithms requires
extensive analysis and understanding of the behavior of the
communicating nodes under a given mobility scenario. One of the
good metrics to understand the performance of such protocols is
the reliability of message delivery.
In this paper we present analytical models of the average
reliability of short (chat-like) message delivery in mobile wireless
networks as a multivariate function of the transmission range,
movement area dimensions, number of servers (base stations) and
message deadline (lifetime) under moderate realistic assumptions
which can be easily relaxed and extended.
Simulation results show that our analytical models give very
good estimation of the average reliability of message delivery.
