Distributed semantic algorithm for power constrained publish/subscribe routing

Abstract

In this paper, context awareness is exploited by defining semantic relations among sensor nodes. Data is routed in a multi-hop network after the establishment of semantic based communication links between sensors. Minimizing the energy consumption is a critical issue in resource constrained sensor networks. Context awareness introduces a new level of intelligence that can be exploited in order to improve the efficiency of communication networks. The semantic routing proposed here is achieved in a completely distributed fashion. Distributed routing has been found to be effective for achieving scalable information dissemination in publish/subscribe communication systems. In this paper a novel method is proposed for designing sensor network ontology and for routing information through the network by using a distributed minimum semantic spanning tree approach. The results demonstrate that it is possible to take advantage of semantics to reduce network load in terms of data dissemination.

Capturing the contributions of the semantic web to the IoT: a unifying vision

“…On the other hand, the multiplication of nodes implies a multiplication of power consumers, and managing energy consumption at the scale of the node leads to energy saving at a more global scale. The use of semantic web technologies to reduce the cost of content transport was already discussed in the description of the associated processes presented by [47] and [45]. However, in these papers, the use of semantic web technologies is not modified to match the constraints of an IoT network.…”

DTA: Dynamic topology algorithms in content-based Publish/Subscribe

“…In recent years, the effort of designing the Pub/Sub system has been made by researchers from the academy and industry [2][3][4]. For the researchers from academy, they focused on the enhancement of the system expression capacity (e.g., content-based routing algorithms and semantic [5,6]) and the compatibility with the new application environments (e.g. P2P network [7,8]).…”
