Distributed Fault-Tolerant Quality of Service Routing in Hybrid Directional Wireless Networks

<p>A hybrid mobile ad hoc network (H-MANET) consists of a group of communicating hosts that form an arbitrary network topology by means of any of several wireless communication media - E.g. free space optics (i.e. infrared laser light) or directional radio frequency technology. H-MANET communications represent a diversification in communication technology necessary to solve the stringent end-to-end requirements of the GIG. Of the many challenges in this complex distributed system the problem of routing based on a predefined set of customer preferences critical to guaranteeing quality-of-service is the focus of this research. Specifically this thesis modifies a cluster based QoS routing algorithm for mobile ad hoc networks with the aim of providing fault-tolerance - a critical feature in providing QoS in the link failure prone environment of mobile networks. Performance of this new fault-tolerant cluster based QoS wireless algorithm is evaluated according to failure recovery time dropped packets throughput and sustained flow bandwidth via simulations involving various node failure scenarios along QoS paths.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
