It provides the researchers a comprehensive understanding of methods … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,657 accessesView PDF Cite

Research ArticleOpen accessIn the author namesPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,693 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAd Hoc Mobile Wireless Networks Routing Protocols - A ReviewGeetha Jayakumar, G. GopinathMobile ad hoc networks(MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad-hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad-hoc network is not a new one, having been around in various forms … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 115,285 accessesView PDF Cite

Research ArticleOpen accessIn the author namesHydroxyapatite-induced Phagocytic Activity by Murine Macrophages in vitroV.K. Gopinath, M. Musa, A.R. Samsudin et al.The aim of the present study was to assess phagocytic activities of murine macrophages (RAW264.7 cell line) to hydroxyapatite (HA) particles. Transmission electron microscope (TEM) was used to assess localization of HA particles in the cells at 7, 15, 30 and 60 min. The HA particles and latex beads, as a control, were also incubated with the cells pretreated with … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,375 accessesView PDF Cite
