Currently, wireless data broadcasting is a very popular data dissemination method for broadcasting public information to a large number of mobile devices at the same time. Access Latency and Tuning Time are the two main parameters to evaluate the performance of a indexing technique of data broadcasting system. Indexing can significantly reduce tuning time by switching clients to turn into doze ...

A Wireless Sensor Network (WSN) consists of sensors implanted in an environment for collecting and transmitting data regarding changes in the environment based on the requests from a controlling device (called base station) using wireless communication. WSNs are being used in medical, military, and environment monitoring applications. Broadcast (dissemination of information from a central node)...

This paper studies broadcasting and gossiping algorithms in random and general AdHoc networks. Our goal is not only to minimise the broadcasting and gossiping time, but also to minimise the energy consumption, which is measured in terms of the total number of messages (or transmissions) sent. We assume that the nodes of the network do not know the network, and that they can only send with a fix...

A novel algorithm is presented for broadcasting in the single-port and duplex model on a completely connected interconnection network with start-up latencies. None of the existing broadcasting algorithms performs close to optimal for packets that are neither very large nor very small. The broadcasting schedule of the new algorithm is based on trees of “fractional” degree. It performs close to o...
