Research ArticleOpen accessIn the abstractLoad Balancing of Distributed Systems Based on Multiple Ant Colonies OptimizationAl-Dahoud Ali, Mohamed A. Belal, Moh’d Belal Al-ZoubiProblem statement: Ant Colony Optimization (ACO) provides a meta-heuristic optimization tool and collective intelligence model to several applications such as routing and load balancing. A lot of work found in the literature on using ACO in load balancing. However, as far as our knowledge, there was no work relating load balancing in distributed systems with ACO. Approach: In this study, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple Constraints for Ant Based Multicast Routing in Mobile Ad Hoc NetworksA. Sabari, K. DuraiswamyProblem statement: A Mobile Ad hoc Network (MANET) is one of the challenging environments for multicast. Since the associated overhead is more, the existing studies illustrate that tree-based and mesh-based on-demand protocols are not the best choice. The costs of the tree under multiple constraints are reduced by the several algorithms which are based on the Ant Colony Optimization (ACO) … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Four Wave Mixing (FWM) in Routing and Wavelength AssignmentTan Saw Chin, F.M. Abbou, Ewe Hong TatThe impact of Four-Wave-Mixing (FWM) is investigated using the proposed Assign Shortest Path First (ASPF) algorithm for wavelength assignment in Routing and Wavelength Assignment (RWA). Results show that ASPF algorithm indulges more FWM crosstalk in high optical channels for all input light power and low input power able to reduce he effect of FWM. The blocking probability due to FWM … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,756 accessesView PDFCite

Al-KhateebProblem statement: Traffic congestion and tidal flow management were recognized as major problems in modern urban areas, which have caused much frustration and loss of man hours. Approach: In order to solve the problem an intelligent RFID traffic control has been developed. It has circumvented or avoided the problems that usually arise with systems such as those, which use image … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 21,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Distance Based Route Maintenance Strategy for Dynamic Source Routing ProtocolMuhammad F. Sjaugi, Mohamed Othman, Mohd. Fadlee A. RasidAlthough DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from the route cache. If alternative routes are not available, the source node, then, will enter route discovery phase to find new routes. We introduced a new … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,316 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterogeneous GPRS-WLAN Integration Based on Ad-Hoc NetworksS. LouvrosIn heterogeneous microcellular networks like 802.11(WLAN)-GPRS, users can roam around through vertical handoffs. The major problem in heterogeneous networks is that they support different QoS requirements and the users suffer sudden changes in data rates. This study proposes certain routing algorithms to extend the service time of mobile handsets in the wireless network with higher available data rate, thus improving … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 6,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnt Colony Based Node Disjoint Hybrid Multi-path Routing for Mobile Ad Hoc NetworkB. Kalaavathi, K. DuraiswamyMobile Ad hoc Networks are characterized by multi-hop wireless links, without any infrastructure and frequent node mobility. A class of ant colony based routing protocols has recently gained attention because of their adaptability to the network changes.
