We study the problem of energy-balanced data propagation in wireless sensor networks. the energy balance property is crucial for maximizing the time the network is functional, by avoiding early energy depletion of a large portion of sensors. We propose a distributed, adaptive data propagation algorithm that exploits limited, local network density information for achieving energy-balance while at the same time minimizing energy dissipation. We investigate both uniform and heterogeneous sensor placement distributions. By a detailed experimental evaluation and comparison with well-known energy-balanced protocols, we show that our density-based protocol improves energy efficiency significantly while also having better energy balance properties. Furthermore, we compare the performance of our protocol with a centralized, off-line optimum solution derived by a linear program which maximizes the network lifetime and show that it achieves near-optimal performance for uniform sensor deployments.

Each year scholars and practitioners from institutions, organizations, and corporations around the world gather for one week to discuss their work and see the work of others from across the wide range of practices that compose the SIGCHI community. the scale and diversity of this gathering offers an opportunity that is special and only available during the short, intense week. During the conferencethere is a session dedicated to the discussion of priorities for us as members of a community, and for the community itself as a part of the fabric of SIGCHI. For the Design Community this is a rather complex endeavor because our constituents are and our fellow communities understand the pursuit of design in a variety of ways. But this embodies the valuable asset that our community has become as one part of SIGCHI. So let's discuss these topics. the Design Community co-chairs invite you to join us at this session for a frank discussion about the state of the Design Community and Design work at CHI 2011 and beyond.

this book constitutes the refereed proceedings of the 5thinternationalconference on Industrial Applications of Holonic and Multi-Agent systems, HoloMAS 2011, held in Toulouse, France, August 29-31, 2011. the 25 revised full papers presented were carefully reviewed and selected from 36 submissions. the papers are organized in topical sections on industrial agents, simulation and modelling, planning and scheduling, smart technical systems, and MAS for unmanned aerial vehicles.
Context-aware systems demand a customized development methodology because they have their own features such as ambiguous system scope, context modeling, and implementing context-dependent services. Furthermore, it has...
