Wireless ad-hoc sensor networks are a new platform in the fields of remote sensing, data collection, analysis, problem solving, and various research studies. They contain nodes that act as transmitters and receivers, and are vulnerable to various attacks and incur various types of loss. Resource exhaustion attacks, once considered just a routing problem, now fall into a new group called "vampire attacks." A resource exhaustion or vampire attack drains a node's batteries, rendering them useless. Vampire attacks are not specific protocols and are hard to spot. This paper examines the identification and protection of resource exhaustion attacks at the routing protocol layer using the PLGP protocols (Parno, Luk, Gaustad, and Perrig). This white paper focuses primarily on detecting and preventing vampire attacks. The proposed method is used to prevent network node exhaustion. ...

Distributed systems require that there should be a coordinator node in the entire system that will perform coordination activity which is needed for the smooth running of other nodes in the system. The paper presented here tells about the Bully Algorithm which gives us the idea about the way in which the modification works when routing of the algorithm goes. Here in this paper we use the AODV (Adhoc on Demand Distance Vector) Routing protocol in comparison with RIP (Routing Information Protocol) for the routing purpose.

The clients stores their data on cloud for data security, for ease of accessing and integrity are prime related. In this paper, the problem of ensuring data integrity and security of data storage provided on cloud from the client while storing data over cloud. To ensuring correctness of data, it assumes that authentication required for uploading and retrieving of data over cloud and these task of allowing by a trusted party (TP) used for exposing risk of cloud storage services on behalf of the cloud client to verify data integrity stored in the cloud. This paper focuses on the data security, we proposed erasure correcting method in the file distribution to the cloud and the client authentication provides the redundancies and guarantees data dependability. By using RSA encryption technique and by calculating hash value with distributed...

Cloud computing is attractive to business owners as it eliminates the requirement for users to plan ahead for pro-visioning hardware and allows enterprises to start from the small scale and increase resources only when there is a rise in service demand. One of the trends in cloud computing is the use of decentralized cloud, where resources are shared between multiple servers instead of one central server. The use of decentralized cloud can reduce task complexity and work efficiency per server by utilizing small amount of resources from various servers. With this emerging trend in decentralized cloud, various methodologies were introduced to implement it. One of the most important methodology that plays a vital role in decentralized cloud is Load distribution. Load distribution can be achieved in various ways and hence different approaches can lead to better ways to distribute load in cloud servers. So by researching various methodologies used in cloud computing, a similar but new load distribution algorithm can be implemented which will be based on current statistics of the server nodes by comparing statistics the resultant best node can be chosen to dispatch the file which is to be uploaded.

Cloud provider must verify the authorized user. If someone try to access the account, data will get leaked. This leaked data will present in an unauthorized place (e.g., on the internet or someone’s laptop). In this paper, we propose Division and Replication of Data in the Cloud for Optimal Performance and Security (DROPS) that collectively approaches the security and performance issues. In DROPS methodology, we have to select the file and then store the particular file in the cloud account. In order to provide security we are going to implement DROPS concepts. Now we divide the file into various fragments based on the threshold value. Each and every fragments are stored in the node using T-Coloring. After the placement of fragments in node, it is necessary to replicate each fragments for one time in cloud. Keywords—Data leakage, cloud security, fragmentation, replication, performance.

Owing to the requirement for low device complexity together with low energy consumption (i.e., long network lifetime), a proper balance between communication and signal/data processing capabilities must be found. A Wireless Sensor Network (WSN) consists of enormous amount of sensor nodes. These sensor nodes sense the changes in physical parameters from the sensing range and forward the information to the sink nodes or the base station. The wireless sensor network consists of small limited energy sensors which are connected to one or more sinks. The maximum energy consumption takes place in communicating the data from the nodes to the sink. Multiple sink WSN has an edge over the single sink WSN where very less energy is utilized in sending the data to the sink, as the number of hops is reduced. If the energy consumed by a node is balanced betw...

In multitasking operating system for the applications request to meeting of time deadlines and functioning in proper real time constraints, To meet the real-time constraints ; in Real time system for scheduling the task, different scheduling algorithms used. Most of the real-time systems are designed using priority based preemptive scheduling algorithm, worst case execution time estimates to guarantee the execution of high priority tasks. The hybrid Algorithm schedules the process on single processor when it is preemptive. The advantage of the proposed algorithm is that it automatically switches between the EDF and ACO scheduling algorithm and overcome the limitation of both the previously discussed algorithms in paper.

Though the benefits are clear, such a service is also relinquishing user’s physical possession of their outsourced data, which inevitably poses new security risks towards the correctness of the data in cloud. A data distributor has given sensitive data to a set of supposedly trusted agents. Sometimes data is leaked and found in unauthorized place e.g., on the web or on somebody's laptop. The owner of the data is called as distributors and the trusted third parties are called as agents. Sometimes the data loss also occurs. Data leakage happens every day when confidential business information such as customer or patient data, company secrets, budget information etc. are leaked out. When this information is leaked out, then the companies are at serious risk. Most probably data are being leaked f...
