In wireless sensor networks (WSN's), our main aim is to ensure the confidentiality of the data which has been sensed, aggregated and communicated to the base node. This will be achieved using key management. Symmetric key management uses only one key for encryption and decryption.Symmetric key management is generally preferred in WSN, because it will consume less battery power, memory and induces less computation overhead. Asymmetric key cryptography uses two separate keys, for encryption and decryption but those two keys are interconnected with complex mathematical algorithm. Since it is using complex mathematical algorithms it will induce huge overhead on power, computation and memory Asymmetric key cryptography is not preferred in WSN. Asymmetrickey cryptography is more secured and efficient when compared to symmetric key cryptography, this paper analyzes various opportunities of implementing asymmetric cryptography in wireless sensor networks.

Review of asymmetric key cryptography in wireless sensor networks

Accidents in railway lines include collision with snags, derailment and human losses due to movements of trains. Railway transportation is usually very safe for passengers, although railway accidents and train derailment still happen. To solve this problem, a railway security system is proposed in this article. Here Ad hoc Wireless Networks are employed, but implementation of these systems poses problems due to the length of railway lines. On the other hand use of Ad hoc Wireless Network promises a very interesting and practical option. With recent advances in wireless communication and in electronics, there has been a reduction in the price, power, and size of sensor nodes. There sensors include a microprocessor, a multi-byte RAM, a short-range, short-wave radio transmitter, and a small power source (like a battery).The main technique and the major aim of this system is to develop a new solution, based on a Adhoc Wireless Networks with the use of WiMAX(Worldwide Interoperability for Microwave Access) for the problems faced in railway lines. The purpose in studying railway lines includes finding new methods to reduce the rate of accidents. © Research India Publications.

Accident avoidance in railway tracks using adhoc wireless networks

In today's day to day life, we may come across the word network. It can be related to mobile phones or internet, meaning that the network is all over the place and if we talk about networks, then first thing that hits our mind is sharing, which can be done via internet or by any other resources. So here in this paper, we are implementing sharing of data by using mobile nodes. It is a fast technique for sharing the data between different locations. Mobile nodes share data with the help of Wireless Sensor Networks (WSNs) which provides a fast and easiest way for connections. © Research India Publications.

Most of the researchers and scientists are striving towards the enhancement of Genetic Algorithm (GA) which is under the field of Bio-Informatics. In general a Genetic Algorithm is solved by using Crossover and Mutation method. Here Crossover refers to a random shifting of a child in order to make new tours and Mutation adjust the Crossover. However, a Genetic Algorithm is efficient in itself, yet there are two problems that can be further optimized to get better results. Those problems are: During the encoding of tour if population is less, it may result in identical solutions, which is invalid. To solve the first problem we need to increase the population size. But on doing so, the time complexity will rise exponentially. In this paper I am proposing a modified Genetic Algorithm which essentially aims at eliminating the above stated problems. Furthermore, I will try to demonstrate this solution by an application that might be used by a detection based database. © Research India Publications.

In India there are many insurance companies providing insurance policies under different terms and conditions. A common man is ignorant about the most suitable policy according to his needs. So we present a paper Smart Insurance decision support system which is based on Crowd sourcing. It is a web application which supports decision making. It acts like an insurance consultant who gives the appropriate opinion to the customers based on the details filled by them like personal information, financial details, family details etc. The policy maker algorithm performs analysis on that data. Based on the result of analysis, description of suitable policies with their links redirected to actual web sites will be displayed to the user. Finally it guides the user so that they can register themselves for those insurance policies which they find suitable. © 2013 IEEE.

In the present era where technology has become a part of our life, every day new applications are developed in every field to serve mankind. Many applications have been developed using GPS (global positioning system) such as aquatic and spacecraft routing, surveying and mapping, precise time reference etc. GPS (global positioning system) enables everyday activities such as banking, mobile phone operations, and even the control of power grids by allowing well harmonized hand-off switching and accurate time. The main contribution of this paper is tracking and transportation of object in a secured way using RWP and GPS. To assure the security of the tracking and tracing application we introduce a method to evaluate the one-hop distance between the target object and all the cooperative nodes in the object's view. A key factor that increases the project's accuracy and performance is GPS, a common example of wireless which can be interfaced to provide location and time information in all weather conditions. GPS has become a widely adopted and useful tool for commerce, scientific uses, tracking, and investigation. We control the ground session with RWP (random way point) using AODV routing protocol.
