Positioning requirements for mobile nodes in wireless (sensor) networks are largely increasing. However for indoors environments most of the existing solutions are expensive in terms of technology or infrastructure. We propose an indoors positioning scheme in which a static user collects self-estimated positions of collaborating peer nodes within radio range as well as the error ranges of these estimations...
Trust and reputation models research and development for distributed systems such as P2P networks, wireless sensor networks (WSNs) or multi-agent systems has arisen and taken importance in the last recent years among the international research community. However it is not always easy to check the correctness and accuracy of a model and even more, to compare it against other trust and reputation models...
Average consensus algorithms are protocols to compute the average value of all sensor measurements via near neighbors communications. They offer a natural tradeoff between the number of messages exchanged among terminals and the accuracy in the computation. Most of the models adopted for the message exchange in the literature, however, neither include explicit rate constraints nor explore the rate...
