Abstract:
With the advances in telecommunication
information technologies, wireless industry has been
showing extraordinary advantage in all aspects of human
life. Particularly in open rural areas which are short of
basic communication facilities and suffer from harsh
geographic and climatic environments, the adoption of
easy-operating and cheap-maintaining wireless
communication appears to be a fast and feasible choice
for telecommunication carriers and service providers to
lay down their own networks. Profit is being made or
expected with certainty from the potential
telecommunication market in rural areas. Hence we
embarked upon finding a refined wireless network
planning method to foster communication construction in
rural areas. A one-pipe-four-layer wireless simulation
model, called Service Model, is highlighted in the paper to
implement the network planning method. The Service
Model collects raw data from given rural areas and
abstracts these data by flowing them through four
technical layers to form the predicted technical wireless
network. Thereafter, a software simulation environment,
BrwsLi, is designed and coded in freeware Scilab to
realize the Service Model for the sake of instantiation.
This simulation environment is able to set up a specified
rural network by constructing topology for the network
on the invented areas, simulate its network traffic, and
evaluate the network performance and economic
efficiency. What's more, Newcastle in KwaZulu-Natal,
South Africa is chosen as the sample of real-world cases to
demonstrate the way of applying the Service Model
practically and present the way of operating BrwsLi
properly.
