transmit group membership lists, and hence group information must be disseminated through unreliable and potentially malicious nodes. In this paper, we propose a local and robust group information dissemination and consolidation protocol, called MembersOnly, that both quickly and accurately transmits group

Abstract We study the problem of achieving global behavior in a group of robots using only local sensing and interaction, in the context of formations, where the goal is to have N mobile robots establish and maintain some predetermined geometric shape. We have devised a simple, general, robust

' localization is subjected to many malicious attacks. Therefore, sensors' locations are not trstworthy and need to be verified before they can be used by location-based applications. Previous verification schemes either require group-based deployment knowledge of the sensor field, or depend on expensive

Spatially distributed genetic populations that compete locally for resources and mate only with sufficiently close neighbors, may give rise to spontaneous pattern formation. Depending on the population parameters, like death rate per generation and size of the competition and mating neighborhoods

contains principal component analysis (PCA) in joint input and output space, factor analysis, and probabilistic PCA; and group 3 contains reduced rank regression (RRR) and partial least squares (PLS) regression. Among the tested methods, only group 3 managed to achieve robust performance even for a non

OFMP is a hierarchical, network management protocol that enables group operations to be executed on the management information bases of all nodes in the group. As long as no faults occur, OFMP ensures that all nodes execute their local operation exactly once in each group operation. If "

is the classification of cancer types (Golub et al [1], Alizadeh et al A common aim, then, is to use the gene expression profiles to identify groups of genes or samples in which the members behave in similar ways. In fact, that task description encompasses several distinct types of objectives. Firstly, one might want

Message-oriented middleware (MOM) is at the core of a vast number of financial services and telco applications, and is gaining increasing traction in other industries, such as manufacturing, transportation, health-care and supply chain management. Novel messaging applications, however, pose some

Abstract:Mobile ad hoc networks have potentialapplications in civilian and militaryenvironments such as disaster recoveryefforts, group conferences, wirelessoffices, mobile info-stations (intourist centers, restaurants, and so on), and battlefieldmaneuvers, making them a focus of currentresearch

in their local communities. Even now, with access to television and the World Wide Web, people live, work, and associate with local group members on a daily basis. It makes sense, therefore, that people's evaluations and emotions would be more influenced by how they fare in relation to a small group
