Wireless Sensor Networks plays important role in our life so they need to be secured. In this paper we will first give introduction of basics of wireless sensor network and code dissemination technique. We will discuss the impact of reprogramming on WSN in parallel. we will introduce technique called Enhanced ECC to make WSN energy efficient.

Advances in micro-electro-mechanical systems have triggered an enormous interest in wireless sensor networks (WSN). WSN are formed by large numbers of densely deployed nodes enabled with sensing and actuating capabilities. These nodes have very limited processing and memory capabilities, limited energy resources and it is envisioned that they will be mass produced, to reduce costs. Several chal...

Minimizing Energy consumption is considered as one of the most important principles in the development of routing protocols for Wireless Sensor Networks (WSN). In this study, we propose a Location based Energy-Aware Reliable routing protocol (LEAR) for WSN based on sensor position and clustering. Geographical routing protocols are efficient and convenient for optimum energy consumption and band...

Wireless sensor network (WSN) is vulnerable to a wide range of attacks due to its natural environment and inherent unreliable transmission. To protect its security, intrusion detection systems (IDSs) have been widely deployed in such a wireless environment. In addition, trust-based mechanism is a promising method in detecting insider attacks (e.g., malicious nodes) in a WSN. In this paper, we t...

The wireless sensor network (WSN) can be applied for many application such as industrial, military application etc., The WSN can be used for sensor nodes to collect the data at the regular intervals. In this paper, we examine the load balancing in clustering method and dual data uploading in wireless sensor networks. To avoid the overloading of any single resource and to optimize the use of max...

Wireless sensor network (WSN) using network coding is vulnerable to pollution attacks. Existing authentication schemes addressing this attack either burden the sensor node with a higher computation overhead, or fail to provide an efficient way to mitigate two recently reported attacks: tag pollution attacks and repetitive attacks, which makes them inapplicable to WSN. This paper proposes an eff...

Wireless Sensor Networks (WSN) represent a new dimension in the field of network research. The cluster algorithm can significantly reduce the energy consumption of wireless sensor networks and prolong the network lifetime. This paper uses neuron to describe the WSN node and constructs neural network model for WSN. The neural network model includes three aspects: WSN node neuron model, WSN node ...

Mobility of sensor node in Wireless Sensor Network (WSN) is one of the key advantages of wireless over fixed communication system. But to track the sensor node in the heterogeneous network is more challenging and difficulties. In heterogeneous system, generally power consumption is more then homogeneous system. Thus, tracking the location of sensor node is not only one of the challenges for loc...

In this paper, a new hybrid routing protocol is presented for low power Wireless Sensor Networks (WSNs). The new system uses an integrated piezoelectric energy harvester to increase the network lifetime. Power dissipation is one of the most important factors affecting lifetime of a WSN. An innovative cluster head selection technique using Cuckoo optimization algorithm has been used in the desig...

Recently, the use of the database paradigm has emerged as a feasible solution to manage data in Wireless Sensor Network (WSN) environments. Various Sensor Network Query Processors (SNQPs) implements in-network declarative query processing that provide data reduction, aggregation, logging, and auditing facilities. These SNQPs view the WSN as a distributed database over which declarative query pr...
