Abstract
The increasing ubiquity of communicating mobile devices and vastly different mobile application needs have led to middleware models for ad hoc networks that simplify application programming. One such system, EgoSpaces, addresses the needs of individual applications, allowing them to define what data is included in their operating context using declarative specifications constraining properties of data, agents that own data, hosts where agents are running, and attributes of the network. In the resulting model, application agents interact with a dynamic environment through a set of views, or custom defined projections of the set of data present in the ad hoc network. This paper builds on EgoSpaces by allowing agents to assign behaviors to views. Behaviors consist of actions automatically performed in response to specified changes in a view. Behaviors discussed in this paper encompass reactive programming, transparent data migration, automatic data duplication, and event capture. Formal semantic definitions and programming examples are given for each behavior.
