Research ArticleOpen accessIn the author namesImpact of Malicious Nodes under Different Route Refresh Intervals in Ad Hoc NetworkP. Suganthi, A. TamilarasiProblem statement: Ad hoc networks are formed dynamically by group of mobile devices co operating with each other. Intermediate nodes between source and destination act as routers so that source node can communicate with the destination node even if it is out radio range and thus eliminating the necessity of infrastructure. Co operation of nodes is a very important feature … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 3 Nov 2011 · 7,302 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSecure Group Key Management for Dynamic Sensor NetworksN. Suganthi, V. Sumathi, R S. MohanapriyhaProblem statement: Key management is an important cryptographic technique for providing security in a dynamic environment of sensor networks. To provide a secure communication among a group of sensor nodes keys should established in an efficient manner. We introduced an efficient and dynamic key management system for dynamic sensor networks. Approach: We pre deployed some of the keying materials in … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,743 accessesView PDF Cite
