We propose algorithms that uses fast graph mining for resolving the network topology to a locally regulated area defined as a component of network topology. Though the IP backbone network should be reconfigured periodically in accordance with environmental changes, reconfiguration results in heavy workload, such as routing re-designs or testing these re-designs for network operators. If a network...
With the increasing development of technologies and reducing costs of materials, satellite networks have been widely investigated both on demand and supply for many years. Multi-Path routing has been applied as an effective method to support end-to-end reliability. But there exist inter-satellite links loss and long end-to-end delay in current multi-path routing due to much frequency of route request...
A wide range of services has been developed for vehicular ad hoc networks (VANETs), ranging from safety to infotainment applications. An essential requirement for such services is that they are offered with quality of service (QoS) guarantees in terms of service reliability and availability. Searching for feasible routes subject to multiple QoS constraints is, in general, an NP-hard problem. Moreover,...
Geographical Routing Technique is a new trend in Wireless Sensor Networks in which the sensor nodes are enabled using Global Positioning Systems(GPS). This helps to easily detect the position of their neighboring nodes. The power consumption is more in the existing routing algorithms, since the nodes build the routing tables and the neighboring node IDs are determined by searching the routing table...
The failure of sensor nodes caused by energy exhaustion or physical destruction may lead to the void areas, so called holes. The hole problem becomes another difficult issue faced by data dissemination protocol based on geographic routing. Most of the existing schemes for the issue tend to construct a static detour path to bypass a hole. The static detour path may lead to uneven energy consumption...
In order to reduce the congestion of Ad Hoc network and increase the speed of routing searching, the link-disjoint paths algorithm based on ant colony optimization is proposed in this paper. The new algorithm introduces the intelligence and positive feedback of ant algorithm to link-disjoint paths algorithm to improve the probability of path optimization, sets the age domain of ant to reduce immersion,...
Multipath routing protocols (MRP) help improve the network quality of service (QoS), including load balancing, fault tolerance (reliability), aggregate bandwidth and delay. While multipaths communication provides better failure-tolerance, their resilience only holds if the multiple paths are selected carefully. Note that selecting an optimal path set is a NP-complete problem. Recently, several algorithms...
In order to realize the core networks of the future utilizing the translucent or transparent optical networks the DICONET vision is presented in this article. Providing ultra high-speed end-to-end connectivity with quality of service and high reliability through the exploitation of optimized protocols and lightpath routing algorithms that will complement a flexible control and management plane is...
