Abstract: "Context discovery using attenuated Bloom filters in context-aware"

Context-aware networks are wireless networks in which the devices

operate and utilize the information about the circumstances to improve

the network performance. A Bloom filter is a space-saving data structure

to represent a set of information. It can represent a variety of

information in a simple and efficient way. In here, we propose a novel

approach to perform context discovery in context-aware networks by using

attenuated Bloom filters. The context information is hashed into Bloom

codes. Each node has an attenuated Bloom filter which contains the

information of neighbors certain hops away.

Based on the results of performance analysis, attenuated Bloom codes

appear to be a very promising approach for context discovery.
