Research ArticleOpen accessPhrase in the titleMobile Node Speed Detection Mechanism in Hierarchical Mobile Internet Protocol (IPv6)Zulkeflee Kusin, Mohamad Shanudin ZakariaProblem statement: IETF has introduced Hierarchical Mobile IPv6 (HMIPv6) to support mobility problem in the next generation Internet Protocol (IPv6). The key concept behind this protocol is the usage of Mobility Anchor Point (MAP) located at any level router of network to support hierarchical mobility management and seamless handover. The distance MAP selection in HMIPv6 causes MAP overloaded as the … …Journal of Computer Science, Vol. 7, Issue 9 · 27 Jul 2011 · 6,614 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance of Improved Directed Diffusion Protocol for Sensor Networks under Different Mobility ModelsK. E. Kannammal, T. PurusothamanProblem statement: In sensor networks, some routing protocols performance differs under different mobility models. In ns2, there are two kinds of directed diffusion protocols, rate based gradient mechanism (diffusion/rate) and probability based gradient mechanism (diffusion/prob). In this research, we proposed a method to improve the performance of Directed diffusion/prob protocol by adding a new interest message propagation mechanism and analyzed … …Journal of Computer Science, Vol. 8, Issue 5 · 25 Feb 2012 · 6,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnveiling the Performance: A Comparative Study of HMAC and RSA Encryption on SHA-512Louis Leonardo, RojaliThe study evaluates critical operations including token signing, verification, and decoding, as well as data transfer efficiency, utilizing the jsonwebtoken library. By benchmarking these operations, we provide insights into the trade-offs between symmetric (HMAC) and asymmetric (RSA) encryption methods, highlighting their impact on performance and security. The results serve as a guideline for developers to make informed decisions when choosing … …Journal of Computer Science, Vol. 21, Issue 12 · 22 Jan 2026 · 1,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Reliability of Routing Protocols as an Important Factor for Road Safety Applications in VANET-based Autonomous CarsAnanto Tri Sasongko, Grafika Jati, Bob Hardian, Wisnu JatmikoThe autonomous cars are considered as a tremendous disruptive innovation in the coming years. They enable a driving automation system to replace human drivers to control the vehicle with better recognition, decision and driving skills and ultimately enhance the road users’ experience and traffic safety. They can communicate with other cars as they are ready with the Vehicle to Vehicle … …Journal of Computer Science, Vol. 16, Issue 6 · 15 Jun 2020 · 7,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractRRDVCR: Real-Time Reliable Data Delivery Based on Virtual Coordinating Routing for Wireless Sensor NetworksVenkatesh, Chanchal Singh Sengar, Kuppanna Rajuk Venugopal et al.Real-time industrial application requires a routing protocol that guarantees data delivery with reliable, efficient and low end-to-end delay. Existing Two-Hop Velocity based Routing (THVR) protocol relates two-hop velocity to end-to-end delay to select the next forwarding node, that has the overhead of exchanging control packets and depleting the available energy in nodes. We propose a Real-Time Reliable Data delivery based … …Journal of Computer Science, Vol. 14, Issue 1 · 3 Jan 2018 · 8,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobility 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 PDFCite
Research ArticleOpen accessIn the abstractDYNAMIC PLANNING BASED SCHEDULING APPROACH FOR WIRELESS SENSOR NETWORKSM. Senthil Kumaran, R. RangarajanEnergy efficiency is an important issue in wireless sensor networks. A sensor node has a microprocessor and a small amount of memory for signal processing and task scheduling. Dynamic Planning is a method is used in this approach it combines the flexibility of dynamic scheduling with the predictability offered by schedulabilty check. Whenever a node wants to transmit data packet … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced RSACRT for Energy Efficient Authentication to Wireless Sensor Networks SecurityP. Kalyani, C. ChellappanProblem statement: The Security in WSN has become a challenge because of its inherent limitations of resources imposed on the sensor nodes. Authentication and key management scheme allows WSNs to be used with confidence and maintains integrity of data in sensor networks. Approach: In the WSN limited resource scenario the generation of public key done and are randomly pre distributed … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 18 Aug 2012 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractCluster Based Data Consistency for Cooperative Caching over Partitionable Mobile Adhoc NetworkP. Kuppusamy, B. KalaavathiProblem statement: Data availability and consistency are foremost issues in Mobile Ad hoc Networks due to the absence of permanent infrastructure. Cooperative caching addresses the data availability issue through coordinating the mobile nodes and sharing the cache copies among them. In the meantime, the mobile node must ensure the staleness of cache copies. The consistency maintenance resolves the staleness of … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 10 Jul 2012 · 6,853 accessesView PDFCite
