Path Diversification is a new mechanism that can be used to select multiple paths between a given ingress and egress node pair using a quantified diversity measure to achieve maximum flow reliability. The path diversification mechanism is targeted at the end-to-end layer, but can be applied at any level for which a path discovery service is available. Path diversification also takes into accoun...

Wireless Mesh Networks (WMNs) being an emerging technology has in recent years received research focus. Considered to be the next step in the evolution of wireless networks, WMNs promises greater flexibility, reliability and performance. In wireless mesh networks, there are multiple potential paths exist between any pair of mesh stations; as each route uses a different set of links with varying...

Clustering is a very popular network structuring technique which mainly addresses the issue of scalability in large scale Wireless Sensor Networks. Additionally, it has been shown to improve the energy efficiency and prolong the life of the network. The suggested protocols mostly base their clustering criteria on some grouping attribute(s) of the nodes. One important attribute that is largely i...

As a promising approach to improve network survivability, reliability and flexibility, topology reconfiguration is extremely important for modern networked infrastructures. In particular, for an existing network and the limited link addition resources, it is valuable to determine how to optimally allocate the new link resources, such that the resulting network is the most robust and efficient. ...

<span>As a result of technological advances in robotic systems, electronic sensors, and communication techniques, the production unmanned aerial vehicle (UAV) systems has become possible. Their easy installation flexibility led these UAV to be used widely both military civilian applications. Note that capability one is however limited. Nowadays, multi-UAV system special interest due abili...

In Heterogeneous mobile ad hoc networks (MANETs) congestion occurs with limited resources. Due to the shared wireless channel and dynamic topology, packet transmissions suffer from interference and fading. In heterogeneous ad hoc networks, throughput via a given route is depending on the minimum data rate of all its links. In a route of links with various data rates, if a high data rate node fo...

Mean Time To Data Loss (MTTDL) has been the standard reliability metric in storage systems for more than 20 years. MTTDL represents a simple formula that can be used to compare the reliability of small disk arrays and to perform comparative trending analyses. The MTTDL metric is often misused, with egregious examples relying on the MTTDL to generate reliability estimates that span centuries or ...

Recently, application of network systems ( e.g. , cloud computing systems) is increasingly prevalent for achieving integration, sharing and efficient utilization various resources. A parallel task in a system has multiple subtasks that can be executed different servers parallel. However, failures any subtask inevitably result the entire cannot complete. To avoid such situation, create some copi...

Mobile Ad hoc Networks are highly dynamic networks. Quality of Service (QoS) routing in such networks is usually limited by the network breakage due to either node mobility or energy depletion of the mobile nodes. Also, to fulfill certain quality parameters, presence of multiple node-disjoint paths becomes essential. Such paths aid in the optimal traffic distribution and reliability in case of ...
