Comparision Of P Self Protection Problem Algorithms For Static Wireless Sensor Networks

In this section, we present the details of proposed protocol. Our protocol implements the idea of probabilities for cluster heads selection based on initial energy and residual energy of sensor nodes as well as the average energy of the sensor network.

3) Secure data aggregation: Fine grain sensing is one of the important compensation of a wireless sensor network which is provided by the large and dense sets of nodes .So to avoid overwhelming amounts of traffic, the sensed values must be aggregated and the aggregation may take place in many places in the network depending on the architecture of the wireless sensor network. For example, the system may average the temperature of a geographic region, combine sensor values to compute the location and velocity of a moving object, or aggregate data to avoid false alarms in real-world event detection. All aggregation locations must be secured [8].

Abstract—Wireless Sensor Network (WSN) is basically a wireless network in which sensor nodes are distributed in any environment condition, to collect the data or information such as temperature, pressure, wind, sea level etc. and accordingly data or information will be passed to the main location. Reliable Trust and Reputation of a node stands for the measure of trust over a certain period of time which can be useful to evaluate the risk of attack from that particular node. We have combined all these parameters in order to risk of attack from a particular node.

The primary objective with this paper deals with how network security systems protect, detect, adapt, recover and/or reconfigured from anomalies in order to provide some desired level of security services. This paper is a strategy for the development of a general security mechanism/countermeasure valuation scheme. The general objective addresses the question, "Given the value of information to be protected and the threat environment, how strong and assured should security mechanism(s) be to provide desired security services(s)?" [DEL98]

As the number of systems to be monitored increases and the chances of attacks increase we

Abstract: In Cyber-Physical Networked Systems (CPNS), the antagonist can inject false measurements into the controller through compromised sensor nodes, which not only threaten the security of the system, but also consume network resources. To deal with this issue, a number of en-route filtering schemes have been designed for wireless sensor networks. However, these schemes either lack resilience to the number of compromised nodes or depend on the statically configured routes and node localization, which are not suitable for CPNS. In this research, we propose a system, which can filter false inoculated data effectively and achieve a high resilience to the number of compromised nodes without relying on static routes and node localization. This adopts polynomials instead of Message Authentication Codes (MACs) for endorsing measurement reports to achieve resilience to attacks. Each node stores two types of polynomials: authentication polynomial and check polynomial, derived from the primitive polynomial, and used for recommending and verifying the measurement reports. Through extensive theoretical analysis and experiments, our data shows that our system will achieves better filtering capacity and resilience to the large number of compromised nodes in appraisal to the existing schemes.

With the furtherance of computer networks extending boundaries and joining distant locations, wireless sensor networks (WSN) emerged as the new frontier in developing opportunities in order to collect and process data from remote locations. A wireless sensor network is a collection of nodes organized in a cooperative manner. Multiple sensor nodes arranged in proximity to sense an event and subsequently transmit sensed and collected information to a remote processing unit or base station. The nodes are able to communicate wirelessly and often self-organize after being deployed in an ad hoc fashion. More than 1000s or even 10,000 nodes are expected. Currently, wireless sensor

The centralized approach is to recognize the most frequently used approach and to diagnose abnormal data readouts caused by a monitoring process, malfunctions of the components of the sensor node, or environmental events. In the centralized failure detection, each sensor node periodically collects its read and sends a packet on the radio to the central base node responsible for identifying faulty sensor nodes in WSN. In this concern, there are many research activities were reported. Gupta and Younis tried to provide a tolerant grouping mechanism to fail to provide the sensor by performing a sensor recovery in the runes in which the bridge has recovered. The mechanism is separated into two phases: 1) detection step for detecting whether or

It is interesting that the biologically inspired approaches to network security because of their similarities between network security and human body resistant to pathogenic attacks. Wireless sensor network is based on low cost and low energy sensor nodes which are connected to physical signals. Such networks are made up of sensors and gateways the data to the end user. This paper used the wireless sensor network nodes and machine learning techniques to distinguish between fake and genuine nodes then desired the inspiration from the human immune system to prevent the role of virtual anti-bodies in system to avoid the fake nodes.

Threshold sensitive Energy Efficient sensor Network protocol (TEEN) [31] was the first protocol that was developed for reactive networks. In this protocol, at every cluster change time, in addition to the attributes, the cluster-head broadcasts to its members. It uses two thresholds namely hard and soft thresholds. The hard threshold is a threshold value for the sensed attribute, it is the absolute value of the attribute beyond which, the node senses this value must switch on its transmitter and report to its cluster head. The soft threshold is a minute change in the value of the sensed attribute that triggers the node to switch on its transmitter and transmit. The nodes sense their environment continuously. The first time a parameter from the attribute set reaches its hard threshold value, the node switches on its transmitter and sends the sensed data. The sensed value is stored in an internal variable in the node, known as the sensed value. The nodes will next transmit data in the current cluster period, only when both the following conditions are

By dividing the WSN into fixed WSN and mobile WSN, it proposes a measure to identify and deal with the sensor node faults. Additionally, it suggested a mechanism for the prediction of the energy consumption of sensor networks.

The remote sensor system is framed by vast number of sensor hubs. Sensor hubs may be homogeneous or heterogeneous. These systems are much conveyed and comprise of numerous number of less cost, less power, less memory and self-arranging sensor hubs. The sensor hubs have the capacity of detecting the temperature, weight, vibration, movement, mugginess, and sound as in and so on. Because of a requirement for heartiness of checking, remote sensor systems (WSN) are normally excess. Information from various sensors is totaled at an aggregator hub which then advances to the base station just the total qualities. Existing framework just concentrate on recognition of Attack in the system. This paper locations investigation of Attack Prevention furthermore gives a thought to how to conquer the issues.
