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 to strategic surveillance. With the proliferation of sensor networks at home, work place, and beyond, securing data in the network has become a challenge. A number of(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)
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)
A smart city uses information technology to integrate and manage physical, social, and business infrastructures in order to provide better services to its dwellers while ensuring efficient and optimal utilization of available resources. With the proliferation of technologies such as Internet of Things (IoT), cloud computing, and interconnected networks,(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)
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)
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 type(More)
