However, this is a slow process because each node is required to manage a high number of friends. Thus, the SIoT issue consists of how to select the right friends that improve the network navigability. The enhancement of the network navigability boosts the search for a service to be rapid but not guaranteed. Furthermore, sending requests from the shortest paths involves the rapid search, but the network lifetime can be reduced due to the number of requests that can be transmitted and processed by the nodes that have low power energy. This paper proposes a new approach that improves the network navigability, speeds up the search process, and increases the network lifetime. This approach aims at creating groups dynamically by nodes where each group has a master node, second, using a consensus algorithm between master nodes to agree with a specific capability, finally adopting a friendship selection method to create a social network. Thus, the friends will be sorted periodically for the objective of creating simultaneously a balance between the energy consumption and the rapid search process. Simulation results on the Brightkite location-based online social network dataset demonstrate that our proposal outperforms baseline methods in terms of some parameters of network navigability, path length to reach the providers, and network lifetime.

[Termes IGN] station GPSRésumé : (Auteur) We review the main studies on mesoscale water cycle from the African Monsoon Multidisciplinary Analysis (AMMA) project. The estimations of precipitation and evapotranspiration, which are the coupling terms between the atmosphere and the surface water cycles, are addressed. Advances in the evaluation of the various components of atmospheric and surface water budgets are reported, and the yearly surface budgets for the Benin and Niger AMMA mesoscale sites are given as examples. The major outcomes and limitations of atmosphere‐surface model coupling exercises are also reported. The paper concludes with suggestions on the research directions on which the community should make future efforts.
