Through semiotic modelling, a system can retrieve and manipulate its own representational formats to interpret a series of observations; this is in contrast to information processing approaches that require representational formats to be specified beforehand and thus limit the semantic properties that the system can experience. Our semiotic cognitive automaton is driven only by the observations it...
A Wireless Mesh Network (WMN) is composed of multiple Mesh Nodes that are connected together using the radio channel and rely on the backhaul capacity available at a limited number of Gateway Nodes. In this paper, we address the problem of assessing the generic cost of a WMN and comparing it with the cost of other supported network solutions, e.g. a cellular network. We restrict our analysis to regular...
We address the problem of energy reduction for a wireless sensor network performing an estimation task and propose an a posteriori measurement selection solution. The energy is saved by selecting in a distributed way a subset of the available measurements for transmission to a central processor. We show how to perform measurement selection for a network of radio-receivers tracking a target via the...
A Wireless Mesh Network (WMN) is composed of multiple Access Points (APs) that are connected together using the radio channel and by a limited number of gateway APs connected to the Internet. In this paper, we address the problem of gateway placement that consists of minimizing the number of gateways while satisfying system performance requirements. Along with the placement problem, the formulation...
