Wireless Sensor Network consists of an enormous number of sensor nodes with data processing and communication facilities. The sensor nodes exceed the gathered data using radio transmitter, to a sink either easily or through other nodes in a multi-hop approach. Wireless sensor network is a power consuming system, since nodes perform on restricted power batteries which decrease its lifetime. The lifetime of the sensor node is based on battery powered devices. Optimally selected modulation and coding is extremely vital technique in wireless sensor networks. This paper provides a detailed study about all the existing energy conservation techniques and also explains about limitations available in the techniques. After having identified the reasons of energy waste in WSNs, we classify energy efficient techniques based on Nodes, MAC Protocols, Networks and Software Levels. We then detail each of Levels.

There are many possibilities a fire can start in an industry or in any remote area. For example, in cotton mills, garments, fuel storages, etc., it may cause due to electric leakages can lead to huge damage. Also it’s a worst-case scenario, causing heavy losses not only financially but also destroying areas surroundings and human being. Robotics is the emerging solution to protect human lives and their wealth and surroundings. The aim here is to design a FIRE FIGHTING ROBOT using embedded system.

In a Wireless Sensor Networks (WSNs) secure data transmission is a critical concern. Clustering of wireless sensor networks is a valuable and practical way to enhance the performance of WSNs. This survey proposes a two secure and efficient data transmission (SET) protocols for Cluster based WSNs, called SET-IBS and SET-IBOOS, by using the identity-based digital signature (IBS) scheme and the identity-based online/ offline digital signature (IBOOS) scheme , respectively. In SET-IBS, the security will base on the hardness of the Diffie-Hellman problem in the pairing domain. SET-IBOOS further decreases the computational overhead for protocol security, which is crucial for WSNs.In SET-IBOOS scheme the security relies on the hardness of the discrete logarithm problem. This survey explains that an identity based protocols have better performance than the existing protocols like LEACH, SEC-LEACH, ROUTING-Leach for CWSNs, in terms of security overhead and energy consumption.

Given an ambiguous query, different users may have different search goals and the accurate links may not be produced. The current existing system does not look through the complete description and content of every link. A novel approach is proposed to infer user search goal by analyzing search engine query logs. First, producing a feedback session which are constructed from user click through logs and can efficiently the information needed by the user. Second the removal of the stop and stemming words from the given query and produce the related links. Third, by using administrator login and user login, storing the user’s history though used from different systems and the mail is sent regarding the recent viewed link to the user’s mail id. Generating the pseudo documents to represent feedback session for clustering. Finally the classified average precision is used to restructure and evaluate the performance of inferring user search goals.

Cloud computing is a promising and emerging technology for the next generation of IT applications. Cloud computing gained attention due to the growth of internet technologies, reduced costs of storage and processing, growth technologies of visualization and advancement in internet security. Cloud computing data security is one of the main challenges in cloud computing. An organization can decide to adopt cloud only on based on benefits to risk ratio. Data security and privacy protection issues are relevant to both hardware and software in the cloud architecture. This paper is focused on the security issues of cloud computing.

Data transmission in the 3G/4G Mobile Data Networks works in increased data rate Due to the collision in the network the delay is increased while data transfer and the energy efficiency reduced. So a new method called Node deployment with routing table estimation is used to reduce the delay in the network. Ant-net algorithm helps to enhance the performance parameters of Adhoc On-Demand Vector to find the shortest path. Probability Density functions are created to establish the node deployment and the routing table generation is done by the Routing table generation method. Queue length and the buffer length calculation are done in the NDRT estimation. Hash key is generated to increase the security of the network.
