Implementing OLSR and Wireless VoIP as Low-Cost Infrastructure Telephony for Rural Area
Abstract: Communication is one
of essential elements in this life, including the people who live at rural areas.
However, telecommunications in rural area especially in Indonesia have many
constraints likeexpensive infrastructure, difficult terrain and electrical
problem. This led to a lot of areas that uncovered bytelecommunication access.
In this paper, we proposed a design and architecture of mobile wireless communication
based on modified openWRT as a solution for low-cost communication and
telephony infrastructure in rural areas. The design combines VoIP over mesh
ad-hoc network as a potential solutionfor cheap calls and use modified embedded
device to save electrical resources as a node to connect each other with multi
hop transmissions. With this approach, we get many advantages such as high
mobility,easy to use, scalable, low-cost implementation, and low power
consumption. This paper presents the measurement result of performance to
provide access telecommunication in several conditions. In addition, this paper
also shows benchmarking results and lifetime of the node that we use in this
prototype. The results show that our node can provide telecommunications access
in terms of making calls with good quality using wireless LAN. To sum this up,
The OpenVoice node is expected to contribute bridging digital divide in rural
areas.
