A Low Energy Time Based Clustering Technique for Routing in wireless sensor networks Farzad Omidi-Kashani, Ouadoudi Zytoune, Driss Aboutajdine, Seyed Mohammad Ata Sharifi Dalooei American Journal of Sensor Technology. 2014 2 (1). doi: 10.12691/ajst-2-1-1 Keywords: wireless sensor networks, energy efficiency, clustering-based algorithm, data aggregation, data compression Context: A Wireless sensor network (WSN) is a collection of tiny sensor nodes that are deployed to monitor the environment. These sensor nodes have limited capabilities, especially the energy reserve and processing ability. So, the routing protocols design for this kind of networks is a crucial challenge. Because these routing protocols should be simple, energy-efficient, and robust to deal with a very large number of nodes, they should also be self-configurable to node failures and changes of the network topology dynamically. The most proposed routing techniques organize the network in clusters where the sensing area is divided into many sub-areas. This paper presents a new algorithm for clustering in WSN based on the node residual energy compared to the network one and allowing a better partitioning of the network area which enhance the data distortion at the sink by using the best data coding rate at the cluster head. The simulation results show that this algorithm allows network stability extension compared to the most known clustering algorithm. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Energy Efficient Secure Firewall and Packet Filtering System in wireless sensor networks Manjuprasad B, Andhe Dharani, Shantharam Nayak American Journal of Sensor Technology. 2014 2 (3). doi: 10.12691/ajst-2-3-2 Keywords: wireless sensor network, LEACH, clustering, key compression, data authentication, confidentiality, integrity Context: Sensor networks play a key role in collecting information from the human unattended and surveillance area. The information collected from any types of networks should be secure in all perspective and that too security in sensor networks is crucial because the information is of auto generated type and it is difficult to distinguish between original and replicated information at receiver side. The existing secure mechanism like cryptographic techniques is too complex and it affects the performance of the sensor networks by dissipating more energy for both computational and communicational purpose. This research work aims to propose a low complex simple secure mechanism for sensor networks which can withstand the simple types of attacks to provide a framework for achieving Confidential, Authentication and Integrity. This security is achieved by adopting a firewall rules and packet filtering in the sensor networks with an efficient clustering mechanism for the resource constrained sensor devices.
