Query: Energy Efficient Broadcast in Mobile Networks Subject to Channel
  Randomness   Wireless communication in a network of mobile devices is a challenging and
resource demanding task, due to the highly dynamic network topology and the
wireless channel randomness. This paper investigates information broadcast
schemes in 2D mobile ad-hoc networks where nodes are initially randomly
distributed and then move following a random direction mobility model. Based on
an in-depth analysis of the popular Susceptible-Infectious-Recovered epidemic
broadcast scheme, this paper proposes a novel energy and bandwidth efficient
broadcast scheme, named the energy-efficient broadcast scheme, which is able to
adapt to fast-changing network topology and channel randomness. Analytical
results are provided to characterize the performance of the proposed scheme,
including the fraction of nodes that can receive the information and the delay
of the information dissemination process. The accuracy of analytical results is
verified using simulations driven by both the random direction mobility model
and a real world trace.
