accepting or rejecting a friendship request when there is incomplete information about the main characteristics and preferences describing the requester. Towards this end, the paper has introduced a novel decision theoretical model of friendship acceptance, with incomplete information, that has been used to build different network structures determined by the different expectations and preferences of its users. The proposed model has the capacity to deal with ambiguous environments and

The authors of this paper aimed to extend their previous work on single follower Stackelberg VDB model. Their previous model only considers one attacker type whereas the approach in this paper proposed Bayesian Stackelberg model that allows the inclusion of multiple attacker types. This feature enables the verifier to obtain a mixed strategy that is optimized with respect to all attacker types' interests and their probability of being faced in the game. Test results showed the proposed model was significantly faster and required less number of verifications to detect manipulations originating from multiple attacker types. The authors analyzed the need and importance of verification moments' randomization and discussed the optimal randomization method to accomplish it. A detailed discussion on the implementation settings of the various model components is presented. The third paper by Robati et al. is entitled "Design and Simulation of Distributed IMA Architectures using TTEthernet: A Model-Driven Approach". Avionics are the electronic systems used on aircraft, artificial satellites, and spacecraft. Avionic systems include communications, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft This special issue is based on selected papers from the Seventh International Conference on Ambient Systems, Networks and Technologies (ANT), which was held at Madrid, Spain on 23-26 May 2016. The conference attracted a large number of scientific papers that contributed to the state-ofthe-art in the areas of pervasive and ambient information systems including social networks, wireless sensor networks, authenticity and internet-of-things. All the papers selected for this special issue has been extended from their original versions and underwent two rounds of rigorous peer-review process. Based on the reviewers' feedback, as well as the evaluations of the guest editors, seven papers were accepted for this special issue from ten invited and submitted papers. The accepted papers cover interesting works on new developments in ambient and networked systems such as internet-of-things, avionics systems, wireless sensors network, and social network. The first paper by Caprio et al. is titled "The Emergence of Inclusive and Exclusive Virtual Communities Determined by the Preferences of their Users". In social network sites (SNs), users are always faced with the challenge of * Elhadi M. Shakshuki
