Wireless mesh networking technology has been extensively used in many practical applications, and the techniques that enhance networks reliability are always research focuses in this field. Wireless routing mechanisms are playing a more and more important role in determining wireless mesh networks reliability. A protection routing mechanism, Protection Ad Hoc On-demand Vector routing (P-AODV), is...
In order to better address the problems like the inefficiency and large expense of various Ad Hoc routing protocols, this paper using OPNET simulation tool for the performance of DSR routing protocol simulation, build a small-scale (30 nodes), medium size (50 nodes) and large-scale (100 nodes) the complexity of the mobile ad hoc network model, the DSR routing algorithm, the average route discovery...
For real-time multimedia communication has strict QoS (Quality of Service) requirements for network, especially it is very sensitive to packet loss rate and delay jitter. When the communication network becomes seriously congested, a Bi-directional Resource Reservation model solution is proposed. This scheme supports the QoS priority and Bi-directional Reservation. The results show that the internal...
As a new networking topology, Wireless Mesh Networks (WMNs) have advantageous properties in terms of robustness, range extension and density, but also have significant potential disadvantages, which determines some classical routing algorithms are not very suitable for WMNs. In this paper, we propose a novel routing algorithm based on the WMNs access scheme design to improve the networks performance...
xAd hoc networks are characterized by multi hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols, compare the performance of two prominent routing protocols for mobile ad hoc networks. xDSR (dynamic source routing) and AODV (ad hoc distance vector routing). A detailed simulation model with MAC and physical layer models is used to study...
