This paper presents distributed bounded-error parameter and state estimation algorithms suited to measurement processing by a network of sensors. Contrary to centralized estimation, where all data are collected to a central processing unit, here, each data is processed locally by the sensor, the results are broadcasted to the network and taken into account by the other sensors. A first analysis...
Virtual Ring Routing (VRR) is an ad-hoc routing protocol that avoids flooding the network. It uses location independent identifiers for packet routing. However, VRR does not take into consideration the amount of energy in nodes, leading to the failure of several nodes in the network. To resolve this problem, we have adopted a hierarchical Distributed Hash Table in the VRR architecture. In the r...
Ad-hoc sensor networks are networks of sensing devices (and other communicating devices) whose goal is to have the sensors “sense” some aspect of their local environment and communicate those values over the network they have created. These type of networks create a number of challenging problems for the following reasons. The sensors that are part of an ad-hoc sensor network are most often low...
