Recently, the cyber physical system has emerged as a promising direction to enrich the interactions between physical and virtual worlds. Meanwhile, a lot of research is dedicated to wireless sensor networks as an integral part of cyber physical systems. A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices that use sensors to monitor physic...

A wireless Sensor network(WSN) is a group of sensor nodes cooperating to form a network over a wireless link based on zero fixed network infrastructure. The main idea is to make sensor node cheap and easily deployed every where to create a omnipresent network with smart geographical distribution.WSN become demanding because of its service towards wide range of applications. But constraints are ...

The Wireless Sensor Network or WSN, in general, are wireless networks consisting of hundreds or thousands of autonomous and compact devices so called sensor nodes. WSN are an emerging area of embedded systems that involve large-scale applications, including monitoring, environmental conservation and industrial control. However, there are still remain many limitations within those, such as energ...

-In wireless sensor network,sensor nodes has limited energy and communication ability due to which it is important to design a routing protocol.Routing protocol helps to increases network lifetime of wireless sensor network. This paper contains various existing routing protocol techniques. Keywords—WSN,LEACH,TEEN.APTEEN, location-based routing protocol

Wireless sensor networks (WSNs) consist of a large number of sensor nodes which are capable of sensing different environmental phenomena and sending the collected data to the base station or Sink. Since sensor nodes are made of cheap components and are deployed in remote and uncontrolled environments, they are prone to failure; thus, maintaining a network with its proper functions even when und...

Modern wireless sensor networks require specific and high degree of security due to their limitation and versatility tasks. The absence of permanent infrastructure makes these networks suitable for many civilian applications. But their limited computational ability and battery resources restrictions makes them vulnerable to many kinds of attacks. This paper presents reliability in Wireless Sens...

A wireless sensor network (WSN) is a highly distributed network of resource constrained and wireless devices called sensor nodes. In the work we consider intrusion detection systems as they are proper mechanisms to defend internal attacks on WSNs. A wide diversity of WSN applications on one side and limited resources on other side implies that “one-fit-all” intrusion detection system is not opt...

Wireless Sensor Network (WSN) is a collection of sensor nodes. A sensor node covers all information which is present in its sensing range. To access the information present in some other sensor range, the networks use a process called Routing. One of the routing problems in wireless sensor network (WSN) is concerned with maximizing the sensor network lifetime while continuously routing the coll...

The recent popularity of applications based on wireless sensor networks (WSN) provides a strong motivation for pursuing research in different dimension of WSN. Node placement is an important task in wireless sensor network and is a multi-objective combinatorial problem. A novel multi-objective ABC (Artificial Bee Colony) algorithm based framework has been proposed in this paper. The framework o...

Scarcity of spectrum is increasing not only in cellular communication but also in wireless sensor networks. Adding cognition to the existing wireless sensor network (WSN) infrastructure has helped. As sensor nodes in WSN are limited with constraints like power, efforts are required to increase the lifetime and other performance measures of the network. In this article, the authors propose Doubl...
