In recent years, various P2P network applications, Napster, Gnutella, WinMX, Winny and many others, have been developed. But it is difficult to find out suitable information resources and to guarantee practical response time by using distributed systems with simple search functions. Furthermore, most of applications are based on overlay networks with unstable network topology and query messages...

Ad-hoc Network is new paradigm of wireless communication for mobile host. In MANETs some of the nodes do not take part in forwarding packets to other nodes to conserve their resources such as energy, bandwidth and power. The nodes which act selfishly to conserve their resources are called selfish nodes. The selfish nodes are engaged to reduce data availability and produce high communication cos...

Computing and maintaining network structures for efficient data aggregation incurs high overhead for dynamic events where the set of nodes sensing an event changes with time. Moreover, structured approaches are sensitive to the waiting time that is used by nodes to wait for packets from their children before forwarding the packet to the sink. An optimal routing and data aggregation scheme for w...

Large-scale web search engines are composed of multiple data centers that are geographically distant to each other. Typically, a user query is processed in a data center that is geographically close to the origin of the query, over a replica of the entire web index. Compared to a centralized, single-center search engine, this architecture offers lower query response times as the network latenci...

In wireless sensor networks the management & control of packet forwarding among sensor nodes is a major issues. Wireless Sensor networks can be deployed in various applications namely environmental monitoring e.g. volcano detection, distributed control system, detection of radioactive sources, agricultural and farm practices, internet, military and surveillance. Since the WSN nodes battery ener...

the ability to discover services in mobile ad hoc network (manet) is a major prerequisite. cluster basedcross layer intelligent service discovery for manet (cbisd) is cluster based architecture, caching ofsemantic details of services and intelligent forwarding using network layer mechanisms. the cluster basedarchitecture using semantic knowledge provides scalability and accuracy. also, the mini...

With the advent of the Internet of Things and Industry 4.0 an enormous amount of data is produced at the edge of the network. Due to a lack of computing power, this data is currently send to the cloud where centralized machine learning models are trained to derive higher level knowledge. With the recent development of specialized machine learning hardware for mobile devices, a new era of distri...

Search Engines are used by people on a daily basis to retrieve information from the web. When an ambiguous word is present in a query, specific sense of the keyword is not considered during the search process. Search engines return a large amount of web pages as results from all the possible contexts. Users tend to browse only few pages. Improving quality of retrieved results is a challenge and...

In this paper, we present a semantic-driven kwalkers-based search scheme, called S2P2P, for data information dissemination and query routing in unstructured peer-to-peer (P2P) networks. In S2P2P, each peer maintains its observation on the semantics of received queries (demands) and data information (supplies), as well as a local view on network topology. On top of this, each peer, in line with ...
