Resilience Routing in AdHoc Networks. A decision based routing tree mechanism that can establish routes in adhoc network, which may than be configured into logical dual ring. Also a system is proposed to embed the QoS mechanisms, resilience and reliability features from RPR.
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 …
