چکیده
As computing devices and their users become increasingly mobile, the demand for information about the environment, or context, becomes of significant importance. Applications must be able to adapt themselves to the changing environment to satisfy users’ demands and to ensure that the application’s resource usage matches the environment’s capabilities. However, using traditional means, acquiring this context information can be very expensive because collecting it usually requires communication among mobile devices. In this paper, we explore the possibility of collecting reasonably accurate context information passively. Specifically, this paper introduces a framework for defining passively sensed context through network overhearing, which allows users to define context metrics without the requirement of added communication cost. We use this framework to build a small suite of commonly used context metrics and evaluate the quality with which they can reflect ground truth. Keywords-context-awareness, adaptation, mobile computing, framework

Passive Network Awareness for Adaptive Mobile Applications TR-UTEDGE-2006-002
In pervasive computing, adaptation is essential to applications. However, adaptation requires an up-to-the-minute understanding of the state of the environment, which often comes with a significant added cost in terms of computation and communication. In this paper, we explore possibilities for measuring the degree of mobility in dynamic ubiquitous networks. Existing measures of mobility degree...

متن کاملConstrained consumable resource allocation in alternative stochastic networks via multi-objective decision making
Many real projects complete through the realization of one and only one path of various possible network paths. Here, these networks are called alternative stochastic networks (ASNs). It is supposed that the nodes of considered network are probabilistic with exclusive-or receiver and exclusive-or emitter. First, an analytical approach is proposed to simplify the structure of t...

The development of routing protocols for mobile ad hoc networks is a challenging and active research area, and a variety of approaches have been developed. Among them, geographic routing strategies use knowledge of the devices’ physical positions to achieve efficient routing performance – a critical goal for networks of resource-constrained devices. Strategies have also been developed to perfor...
