Abstract
Wireless broadcast has been increasingly used to
deliver information of common interest to a large number of users.
There are two major challenges in wireless broadcast: the unreliable
nature of wireless links and the difficulty of acknowledging
the correct reception of every broadcast packet by every user when
the number of users becomes large. In this paper, by resorting to
stochastic geometry analysis, we develop a network coding based
broadcast scheme that allows a base station (BS) to broadcast
a given number of packets to a large number of users, without
user acknowledgment, while being able to provide a performance
guarantee on the probability of successful delivery. Further, the
BS only has limited statistical information about the environment
including the spatial distribution of users (instead of their exact
locations and number) and the wireless propagation model. Performance
analysis is conducted. On that basis, an upper and a
lower bound on the number of packet transmissions required to
meet the performance guarantee are obtained. Simulations are
conducted to validate the accuracy of the theoretical analysis.
The technique and analysis developed in this paper are useful for
designing efficient and reliable wireless broadcast strategies.
