In this paper we present a self-organizing, singlehop clustering scheme, which is based on partitioning sensor networks into several disjoint cliques. Clustering sensor nodes into small groups is an effective method to achieve scalability, fault tolerance, load balancing, routing etc. Here, we develop and analyze maximal clique based cluster-first technique(More)
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—Over the past decade, the application domain of wireless sensor networks has expanded steadily, ranging from environmental management to industry control, from structural health monitoring(More)
– At present, the mostly used and developed mechanism is hardware virtualization which provides a common platform to run multiple operating systems and applications in independent partitions. More precisely, it is all about resource virtualization as the term 'hardware virtualization' is emphasized. In this paper, the aim is to find out the advantages and(More)
In this paper we have proposed an energy efficient clique based clustering and routing scheme for wireless sensor networks. Developing energy efficient routing protocol is one of the major challenges in wireless sensor networks. Since the Sensor Nodes (SN) are small-sized battery operated devices, energy conservation is considered a critical factor in(More)
Wireless Sensor Network (WSN) consists of a large number of small sensor nodes (SNs) that are usually deployed in hostile environments. These nodes are vulnerable to a number of security attacks and it is difficult to implement complex cryptographic schemes in SNs due to their resource constrained nature. Hence, WSNs need energy efficient and secure(More)
— A web log or blog in short is a trendy way to share personal entries with others through website. A typical blog may consist of texts, images, audios and videos etc. Most of the blogs work as personal online diaries, while others may focus on specific interest such as photographs (photoblog), art (artblog), travel (tourblog), IT (techblog) etc. Another(More)
Wireless Sensor Networks (WSNs) consist of small nodes equipped with sensing, data processing and radio transmission units. A number of clustering, routing, power management and data aggregation protocols are specially designed for WSNs where energy awareness is an essential design issue. Due to the resource constrained nature of sensor nodes, innovative(More)
– Generally, a graph G, an independent set is a subset S of vertices in G such that no two vertices in S are adjacent (connected by an edge) and a vertex cover is a subset S of vertices such that each edge of G has at least one of its endpoints in S. Again, the minimum vertex cover problem is to find a vertex cover with the smallest number of vertices.(More)
