As the number of people using wireless networks is increasing, the need to reduce the
vulnerability of wireless networks from node or link failures that cause loss of data is
becoming a priority. Also the present techniques and topologies used for wireless
networking are not sufficient to handle the traffic load even if we solve the issues of
reliability and resilience. Packet loss or delay is increasingly likely due to the increase in
the number of packets as technology is evolving and more video and voice packets along
with the data packets are being transmitted. Only the efficient and intelligent use of the
shared medium can solve the problem and help in avoiding the collision or delay among
the packets using a newly proposed intelligent topology.
Wireless technology offers the potential to replace wires from many applications,
particularly for the rapid deployment of networks for permanent or temporary use. Fiber_
optic metropolitan area networks (WAN) provide security and resilience. A target of the
research was to match this in the wireless environment. This research investigates the
suitability if using wireless technology for the establishment of a MAN by adding
features to enhance resilience. We proposed a mechanism that may be rapidly deployed
and provide automatic configuration.
Research work and simulation design has been used to develop a new wireless network
topology for an efficient and intelligent packet transmission by identifying reliable routes.
This novel idea will help give wireless as well as mobile technology a clear edge over
wired technology, not only in the case of mobility but also in the case of security of data
and other services. A decision based routing tree mechanism has been developed, that can
establish routes in an ad-hoc network which may than be configured into a logical dual
ring. At the same time the proposed system proposes to embed the quality of service
mechanisms, resilience, and reliability features from RPR.
The simulations were created using Microsoft Visual Studio.Net for the Decision based
routing algorithm. The results were compared with an existing LAR algorithm. We have
obtained 95% confidence intervals on all the performance analysis results to indicate
accuracy.
