Research ArticleOpen accessIn the abstractPriority and Random Selection for Dynamic Window Secured Implicit Geographic Routing in Wireless Sensor NetworkZurina Mohd Hanapi, Mahmod Ismail, Kasmiran JumariProblem statement: Sensor nodes are easily exposed to many attacks since it were deployed in unattended adversarial environment with no global addressing and used for critical applications such as battlefield surveillance and emergency response. While the sensor also needs to act as a router to relay a message to a required recipient, then this increased the vulnerabilities to a network … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,652 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimal 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 accessIn the abstractEnergy Aware Optimal Routing for Wireless Sensor NetworksS. Chandramathi, U. Anand, T. Ganesh et al.Wireless Sensor Network (WSN) is a collection of autonomous devices with computational, sensing, and wireless communication capabilities. The sensor nodes are low cost, multi-functional devices that are densely deployed either inside the phenomenon or very close to it and are often powered by independent power sources. The lifetime of such sensor nodes show a strong dependence on lifetime of the … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,645 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordRRDVCR: 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 PDF Cite

Research ArticleOpen accessAll words, across the recordEfficient Scheduling of Packets in Wireless Sensor Networks Using Priority Based Scheduling ApproachB. Booba, T.V. GopalThe packet scheduling is essential and plays an important role to sense the element nodes with resource constraints in Wireless Networks. The packet scheduling scheme also scale the energy consumption and end-to-end information transmission delay in time period and non-real-time information packets during wireless transmission. The proposed Priority based Packet Scheduling (PPS) technique has a tendency to overcome the issues … …Journal of Computer Science, Vol. 11, Issue 1 · 9 Aug 2014 · 7,091 accessesView PDF Cite
