Abstract
As a sub-project of the joint project
entitled “A Mobile Electronic Commerce
System,” this project, named “Wireless
Network Protocols for Mobile Electronic
Commerce Systems,” attempts to design
wireless network protocols to enable mobile
E-commerce. We will carry out this project in
a three-year span.
In the third year, we studied the
behavior of packet forwarding in ad hoc
networks with high node density and
proposed a mathematical model to analyze
the probability distribution of the packet
transmission hop counts. We found that in
wireless ad hoc networks, when the routing
protocol is flooding, the behavior of packet
forwarding is analogous to the ripples
radiating by dropping a stone into a lake. As
ripples radiate, the packet reaches the
destination.
To efficiently analyze the data packet
transmission for mobile electronic commerce
systems in wireless ad hoc networks, taking
many system parameters and node mobility
models, we proposed a mathematical model
to calculate the hop count needed for the
packet from the source to the destination and
via numerical simulations, we verified the
correctness of the mathematical model.
Finally, based on the analytical results, we
observe the impacts of different flooding
schemes on the wireless ad hoc networks.
