Leadership Election. A home Audio/Video (AV) network consists of several devices (such as au- dio, video, gateway and legacy audio products) which may be produced by competing manufacturers and distributed across a user’s home. The net- work is an SoS: it exhibits the dimensions typical of an SoS as described in [FFI+13]. • The individual Constituent Systems (CSs) exhibit a (potentially) wide variation in autonomy. They all operate at the behest of the user, but the fact that they may be legacy or well known systems means that they may only offer a limited degree of controllability from the point of view of the SoS. • The CSs exhibit operational independence; they provide stand-alone streaming or content browsing experiences, e.g. watching TV or select- ing music to play. • The CSs are typically distributed in different zones/rooms, the AV con- tent can be local or remote, and the location of content source is often transparent to the user. • Geographical distribution leads to emergent behaviors such as making sound follow the user around, driven by contracts between streaming and clock systems. • The CSs undergo evolutionary development. The stakeholders will have an evolution vision that is not necessarily compliant with that of the system’s manufacturer. • There is dynamic reconfiguration behavior in that products join or leave the SoS during streaming or browsing operations; products can be turned off by users or enter power-saving mode. • While products have no interdependence, CSs rely on each other in order to deliver the emergent behavior that fulfills the SoS goal. Constituent systems may join or leave the network at any time, but a consis- tent user experience (such as a playlist, current song, etc.) must be provided, and this requires availability and consistency of the system configuration data. In order to do this, a publish-subscribe architecture is employed. In this SoS, the chosen architecture requires that the underlying network is able to elect a leader from among the CSs, where the leader is responsible for dis- tributing the global system configuration (containing e.g. network time and current playlist) to the followers in the SoS. As there is no centralised control, the ability to elect a leader is a required emergent property of the SoS: the way that the nodes interact must produce behaviour that individual nodes cannot produce on their own. In the following study, we present a CML model that captures this emergent behaviour.
Leadership Election. The Leader will be elected on October 28, 2017. The first Leader shall be elected by a majority of the members. The LEC shall determine the minimum period of membership for voting in the Leadership election so as to ensure the equality of opportunity of all members to vote. That minimum period of membership shall be at least 21 days, but may be higher to ensure fairness in the distribution of ballots. The period of eligibility to vote will be determined in a manner that ensures the equality of franchise of all members regardless of geography is respected and ensured. For greater certainty, this means the Leadership rules and process must provide an adequate period of time for ballots to be received and cast by the elector on, or before, the Leadership election date. To ensure that membership eligibility requirements are met, reproduction of Canadian or Alberta government issued photo identification must be provided by the elector with their completed ballot, in order for the ballot to be considered valid. The system used to elect the first Leader need not be used for subsequent Leadership elections. The members of the UCP may determine an alternative method of electing future Leaders. At a minimum, a Leadership review vote will be conducted at a convention and general meeting after a general election where the UCP does not form the government, and otherwise as may be specified in the constitutional documents.
