Data centric routing pdf documents

Without a unique identifier, gathering data may become a challenge. We aim to update the reader with the current status of research in this realm. Information centric networking icn research challenges. Therefore, a system that is datacentric is one that acts directly on data, and one that is documentcentric acts on documents. Sr technical university, avadi, chennai, india praveenkumarrao.

Id exists draftmendesicnrgdabber04 information centric routing for opportunistic wireless networks. To overcome this challenge, some routing protocols gather route data based on the description of the data, i. Data centric routing protocols in wireless sensor n etworks. A comparative study of wireless sensor networks and their routing protocols. Pdf a comparative study of wireless sensor networks and. Data centric routing protocols in wireless sensor n. Modelling datacentric routing in wireless sensor networks krishnamachari, estrin 2002.

This concept of what is data and what is a document is commonly misinterpreted. Data centric based routing protocols for wireless sensor. Rumor routing algorithm for sensor networks braginsky. The key features route setup and data dissemination are explained in detail.

The implementation of the aodv protocol was used as a basis for the implementation of the magnetic routing protocol. Datacentric routing protocols in wireless sensor network. Hopbyhop authentication in content centric networkingnamed data networking. Simulation of a data centric routing protocol for mobile. Specifically data centric, location based and hierarchical protocol is designed where energy awareness is taken into consideration. Introduction sensor is a device that produces a reckonable response to a change in a physical condition, such as temperature, pressure and weight etc. Comparative study and analysis of data centric routing. Index terms wireless sensor network, data centric approach, directed diffusion, spin, wsn routing protocol. In this paper, datacentric routing protocols are investigated.

Adaptive beacon placement bulusu, heidemann, estrin 2001 0. Datacentric routing protocols datacentric protocols differ from traditional addresscentric protocols in the manner that the data is sent from source sensors to the sink. In addresscentric protocols, each source sensor that has the appropriate data responds by sending its data to the sink independently of all other sensors. Both protocols are simulated with the network simulator ns2 see section 4. Data centric routing scheme very large number of sensors impossible to assign specific ids. This protocol differs depending on the application and network. Data centric routing data aggregation data storage holger karl, andreas willig, protocols and architectures for wireless sensor networks, wiley 2005. A data destination node, also called a sink, initiates a query for some desired data, which is forwarded towards the hosting sensors alkaraki and kamal, 2004. Data contents documents containers therefore, a system that is datacentric is one that acts directly on data, and one that is documentcentric acts on documents.
