On the Data Dissemination in WSNs

Data dissemination has been put forward as an important mechanism for WSN. The dissemination schemes allow sink nodes to diffuse information in the network. It is known as an energy-consuming phase. In this paper, we propose to resolve this problem in two steps: firstly using a localized self-organization scheme which generates a non-directed backbone; secondly, sink node sends a request through this backbone to create a directed dissemination structure in the network. Our scheme effectively reduces the data traffic during the dissemination phase and saves energy when compared to other schemes. It is also extended to run properly in multiple sinks and mobile sink scenarios. The results also put forward the benefits of using a self-organization scheme for data dissemination.
