Research ArticleOpen accessAll words, across the recordA Fast-and-Fair Collision Resolution Protocol Tailored for Ad Hoc Wireless NetworksMarcos F. Caetano, Lucas M. Guimaraes, Jacir L. BordimWireless technologies have permeated a significant number of devices over the years. On the other hand, Medium Access Control (MAC) protocols strive to deal with an increasing number of contending nodes on crowded frequency bands. This work presents an efficient medium access control resolution protocol. The proposed protocol, termed Collision Resolution Protocol (CRP), uses pulse/tone signaling that works in both … …Journal of Computer Science, Vol. 12, Issue 8 · 1 Nov 2016 · 7,140 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMobility and Handover Technique in Heterogeneous Wireless NetworksRadhwan Abdullah, Zuriati Zukarnain, Farzaneh Masoumiyan, Azizol AbdullahThe management techniques for Mobile IPv6 between different wireless technologies are very important to complete the handover process with the least possible delay. In the fast handover, when a mobile node moves to another network, it needs to do handover operations. These operations have a severe impact on the handover latency. This paper proposes an Enhanced Advanced Duplicate Address Detection … …Journal of Computer Science, Vol. 11, Issue 3 · 31 Mar 2015 · 6,752 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCLUSTER BASED CACHE CONSISTENCY USING AGENT TECHNIQUE IN MOBILE ENVIRONMENTShanmugarathinam Ganesarathinam, Vivekanandan KanniappanCaching is an essential mechanism in mobile environment. Mobile node makes access dynamic changing data object to their server and to get the interested data to keep their own as local copies in the cache. If the server database is updated, the data cached in mobile client is invalidated and it becomes inconsistent between client and server. In this study … …Journal of Computer Science, Vol. 10, Issue 4 · 19 Dec 2013 · 6,487 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordLink Stability with Energy Aware Ad Hoc on Demand Multipath Routing Protocol in Mobile Ad Hoc NetworksSenthil Murugan Tamilarasan, Kannan EswariahMobile Ad Hoc Network is one of the wireless network in which mobile nodes are communicate with each other and have no infrastructure because no access point. The MANET protocols can be classified as proactive and reactive routing protocol. The proactive routing protocols, all nodes which participated in network have routing table. This table updated periodically and is used to … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,505 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAnalytic Performability Model of Vertical Handoff in Wireless NetworksGowrishankar, G. N. Sekhar, P. S. SatyanarayanaProblem statement: The next generation wireless systems should be designed to support heterogeneous traffic with seamless mobility. A single network alone cannot cope up with such heterogeneous requirements. Hence it is desirable to interoperate between diverse and complementary Radio Access Technologies (RATs). In such system, user will switch between different Radio Access Technologies (RATs) to satisfy the User/application requirement and … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,230 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOptimal Power Control with Overhearing Avoidance for Wireless Sensor NetworksM. Ramakrishnan, P. Vanaja RanjanProblem statement: Extending lifetime of the battery operated wireless sensor nodes through the design of low power medium access control protocols dealt in this study. Approach: In this study energy efficient Optimal Power Control MAC with Overhearing Avoidance (OPC-OA) was proposed. The transmission power of every node was dynamically changed for the optimal connectivity between nodes. The optimal transmission power … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,131 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,556 accessesView PDF Cite
