• Static community situation based model

has its own cooperation model, the static
community situation based cooperation
model.

but the way to design cooperation itself was not
discussed. Therefore, we arrived at a decision that
a new cooperation model is needed for intuitive
design of a community's cooperation. Before we
describe our model in detail, please refer to the
related works introduced in section 6.

• It also has security policies such as soci-

ety policy, community policy, and member
policy, so that it solves conflicts in a com-
munity computing system.

Static Community Situation
Based Cooperation Model

To find an appropriate cooperation model for
community computing, we surveyed existing
cooperation models. In a number of previous
works, cooperation is used, but in most cooperation
models, cooperation is described as a predefined
static program called a recipe, plan, or skill. The
ways to realize cooperation have been introduced,

As a cooperation model for community comput-
ing, in this chapter, we propose the community
situation based cooperation model. The idea is that
cooperation is executed according to community
situations. To provide dynamic pervasive services,
context-awareness and/or situation-awareness are
