This paper presents a cooperative localization approach for mobile nodes using wireless and ranging devices. We consider scenarios where node mobility follows stop-and-go behavior; we can then utilize the different movement states of nodes as an input to our localization approach. In the proposed method, each node autonomously finds among its surrounding nodes the ones that do not seem to move, and...
In this paper, we propose an environment to support evaluation of network-aided emergency support systems. We provide an original language to describe the behavior of rescue teams, medical teams and sufferers in disaster areas. This language allows to describe reactive behavior in which actions are determined depending on their locations, surroundings and information received from emergency support...
In this paper, we propose a method to improve the performance of parallel and distributed simulation of multi-hop mobile wireless networks. We assume that the simulation field is divided into several pieces and is simulated by multiple parallel processes which synchronize conservatively, i.e., without violation of causality. The basic idea of our approach is to predict the lower bounds of timestamps...
A new design method is proposed for multiple-stage combline bandpass filters made of stripline resonators. The Grayzel transformation is used for separating the adjacent coupling of each resonator and decomposing the filter into pairs of two coupled resonators. After the design is finished, identical resonators are equally spaced with auxiliary capacitors, which are of a simple structure so that they...
