One of the major issues in wireless sensor network applications is the way how to minimize energy consumption in the process of data transfer. Data in wireless sensor networks should be aggregated in order to save energy and bandwidth. There are lots of works on the area of fault-tolerant and efficient data aggregation for WSNs in different approach. In this paper an efficient fault tolerant data...
In the past decades the advancement in the area of database management systems shifts towards multimedia. Multimedia information is very expressive, self explanatory, narrative, etc. Now a day the development of digital media, advanced network infrastructure and the easily available consumer electronics makes the multimedia revolution to run in an alarming rate. Inline with the advancement of database...
Advances in wireless communication and embedded electronic systems have revolutionized everyday life via inter-networking sophisticated tiny and useful devices. Mobile RFID (mRFID) systems make it possible to get information about entities through portable devices including mobile handsets, PDAs, laptops, etc. RFID tags consist of secret information that can be accessed by an authorized mobile user...
Routing scenario in ad hoc networks is different from infrastructure-based wireless networks; since in ad hoc networks each node acts as a router and is responsible for managing topological information and ensuring correct route learning. Although a number of secure routing protocols have been proposed so far, all of them have certain advantages and disadvantages. Hence, security in ad hoc networks...
In this paper, we suggest an extended security approach for Bluetooth's point-to-multipoint communication. Bluetooth specification defines the basic security measures like, key generation, authentication and encryption for a piconet- which is the basic network unit of maximum 8 active Bluetooth devices. How ever, very little effort has been given so far on point- to-multipoint communication security...
Secure multicasting is one of the major requirements for today's communication arena. And for any kind of secure communication, a key-distribution scheme is the most sensible part. Being a highly promising, low-cost, and emerging wireless technology, Bluetooth has key distribution supports for secure multicasting over its unit one-hop network, piconet. Bluetooth core specification defines basic security...
