In the network research area, establishing of network in a real time scenario is very difficult. A single test takes a large amount of time and cost. So implementation of a whole network in real world is not easily possible and very costly too. The simulator helps the network developer to check whether the network ...

Packet erasure is one of the fundamental and inevitable characteristic in data transmission and data storage system. For example routers may drop a packet due to congestion. Similarly a file in a data storage system can be erased due to component failures. The problem of packet erasure exuberates for data transmission on wireless channel due ...

Cloud computing offer IT services to the users worldwide on the basis of pay-as-you-go model. Cloud computing refer to network based services which appear to be provided by real server hardware, which in fact are served up by virtual hardware, simulated by software running on one or more real machines. These networked based services and ...

In just the past few years, wireless LANs have come to occupy a significant niche in the local area network market. Increasingly, organizations are finding that wireless LANs are an indispensable adjunct to traditional wired LANs, to satisfy requirements for mobility, relocation, ad hoc networking and coverage of locations difficult to wire. One of the ...

Wireless Sensor Networks (WSNs) are an important for monitoring distributed remote environments. As one of the key technologies involved in WSNs, nodes fault detection is indispensable in most WSN applications. It is well known that the distributed fault detection scheme checks out the failed nodes by exchanging data and mutually testing among neighbor nodes in ...

Wireless network node uses broadcasting technique for data transmission. There exist many protocols like simple routing, table driven routing protocol, on demand routing protocol for transmission and each method has its own conflicts. Here, the authors are presenting a new approach by using dynamic topologies with online local broadcasting algorithm called time sequence scheme. This ...

Wireless communication technologies continue to undergo rapid advancement. In recent years, there has been a steep growth in research in the area of Wireless Sensor Networks (WSNs). Sensor nodes are small devices with sensing, computing and wireless communication capabilities. Such devices form WSNs which can be used for many applications like gathering of environmental data ...

Internet Protocol (IP) traceback is the technology to give security to internet and secure from the internet crime. IP traceback system is also called as Flexible Deterministic Packet Marking (FDPM) which builds such a defense mechanism which has ability to find out real source of attacks on packets that traverse through the network. While a ...

Wireless Sensor Networks (WSNs) has been a wide research topic for more than a decade. Typically, a WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions. These sensors generate report over the network on the occurrence of any event. For a WSN to provide better reliability and improved lifetime, an efficient ...

In recent time, data is exponentially increasing so there is problem in quick search. Time, storage & processing also main issues for big data so optimization can be done by implementing bloom filter in it. Hadoop is a bunch of technology & have capacity to store large amount of data on data nodes. So, various ...
