Research ArticleOpen accessIn the abstractParticle Swarm Optimization-Based Routing Protocol for Clustered Heterogeneous Sensor Networks with Mobile SinkR. Sudarmani, K.R. Shankar KumarIn Wireless Sensor Networks (WSN) sensor nodes with sensing, computing and communication infrastructure are randomly deployed and organized as clusters. Most of the existing sensor networks focus on homogeneous in which the cluster heads are changed periodically. To improve the lifetime of energy constraint battery powered WSN and to avoid energy sink-hole problem; Clustered Heterogeneous Sensor Networks (HSN) are analyzed … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 18 Mar 2013 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlooding Attack Aware Secure AODVS. Madhavi, K. DuraiswamyProviding security in a Mobile Ad hoc Network (MANET) is a challenging task due to its inherent nature. Flooding is a type of Denial of Service (DoS) attack in MANET. Intentional flooding may lead to disturbances in the networking operation. This kind of attack consumes battery power, storage space and bandwidth. Flooding the excessive number of packets may degrade the … …Journal of Computer Science, Vol. 9, Issue 1 · 27 Feb 2013 · 7,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelfish Scheduler for Packet Scheduling Based on Packet Weighted Energy Drain Rate in ManetsS. Lakshmi, S. RadhaThe aim of our selfish scheduler based on packet weighted energy drain rate in Mobile ad-hoc networks mainly depends on the available least highest-limit of the residual value of a mobile node. The projected work comprises of mechanisms for detecting the selfish node as well as an attitude called rehabilitate-before-malicious behavior for justifying against the malicious behavior of nodes having … …Journal of Computer Science, Vol. 9, Issue 1 · 6 Feb 2013 · 6,842 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Dummy Packet Distribution Approach for Detection of Routing Misbehavior in Mobile Ad Hoc NetworkT. Sakthivel, R. M. Chandrasekaran, S. Vijay BhanuA Mobile Ad hoc Network (MANET) works on the assumption that mobile nodes are cooperative. On the other hand, in practical, it may not be possible due to selfish, malicious and misbehaving nodes present in the network. These nodes are capable of interrupting the communication process and there is a potential for serious performance degradation. To improve the performance of … …Journal of Computer Science, Vol. 8, Issue 11 · 6 Nov 2012 · 6,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality of Service Aware Reverse Pathad-Hoc On-Demand Distance Vector ProtocolK. G. Santhiya, N. ArumugamMobile Ad-hoc Network (MANET) is aninfra structureless network that does not require any built-in infra structure and central control. Due to very fast mobility of nodes, there will be drastic changes in the network topology. So an adaptive routing protocol is needed for effective and reliable routing in MANET. Ad-hoc On-demand Distance Vector (AODV) routing protocol is the efficient and … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 7,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Impact of Black Hole and Gray Hole Attacks in Mobile Adhoc NetworksUsha, BoseMobile Adhoc Networks (MANETs) are dynamic in nature. Any nodes can join and leave the network at any time. Hence any type of intruders can attack the communication at any time, especially the routing mechanism between the nodes. In this study, we study and understand two types of attacks which cause more damage to the routing performance of MANET; the … …Journal of Computer Science, Vol. 8, Issue 11 · 7 Sep 2012 · 6,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvey on Mobile Ad Hoc Network Attacks and Mitigation Using Routing ProtocolsS. P. Manikandan, R. ManimegalaiMobile Ad hoc Networks (MANET) due to its unpredictable topology and bandwidth limitations are vulnerable to attacks. Establishing security measures and finding secure routes are the major challenges faced by MANET. Security issues faced by ad hoc networks are node authentication, insider attack and intrusion detection. Implementing security measures is challenging due to the presence of limited resources in the … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 6,851 accessesView PDFCite
