Wireless sensor networks have gained much attention these last years thanks to the great set of applications that accelerated the technological advances. Such networks have been widely investigated and many books and articles have been published about the new challenges they pose and how to address them. One of these challenges is node mobility: sensors could be moved unexpectedly if deployed in an uncontrolled environment or hold by moving object/animals.Beyond all this, a new dimension arises when this mobility is controlled, i.e. if these sensors are embedded in robots. These robots cohabit with sensors and cooperate together to perform a given task collectively by presenting hardware constraints: they still rely on batteries; they communicate through short radio links and have limited capacities.In this book, we propose to review new challenges brought about by controlled mobility for different goals and how they are addressed in the literature in wireless sensor and Robot networks, ranging from deployment to communications.

The 7th International Conference on Adhoc, Mobile and Wireless Networks (AdHoc-NOW 2008) was held at INRIA Sophia Antipolis - M editerran ee, on the French Riviera, during September 10-12,2008. The six previous conferences intheserieswereheldinMorelia(2007), Ottawa(2006), Cancun(2005), Vanc- ver (2004), Montreal (2003) and Toronto (2002). The purpose of this conference is to provide a forum for researchers from academia/industry and practitioners to meetandexchangeideas regardingrecentdevelopmentsintheareasofad-hoc wireless networks. AdHoc-NOW 2008 received 110 submissions submitted by authors form the following 33 countries: Algeria, Australia, Austria, Belgium, Brazil, Canada, China, the Czech Republic, Denmark, Finland, France, Germany, Greece, India, Iran, Israel, Italy, Japan, Luxembourg, Macedonia, Norway, Pakistan, Poland, Slovakia, South Africa, South Korea, Sri Lanka, Sudan, Switzerland, Taiwan, Tunisia, the UK and the USA. Each paper was assigned to three members of the Technical Program Committee (TPC). Based on the reviews, we decided to accept 39 submissions as regular papers, 24 of them with 25 minutes' oral presentation time, and 15 as poster presentations. All of the accepted papers appear in this volume. We thank the three invited speakers at this conference, Srdjan Krco (Er- sson, Ireland), Xuemin (Sherman) Shen (University of Waterloo, Canada), and Stephan Olariu (Old Dominion University, USA) for accepting our invitation to share their insights on new developments in their research areas."

This volume constitutes the refereed proceedings of the Third International ICST Conference, ADHOCNETS 2011, held in Paris, France, in September 2011. The 15 revised full papers - selected from 42 submissions - and the 2 invited papers cover several fundamental aspects of ad hoc networking, including security, quality of service, radio and spectrum analysis, mobility, energy efficiency, and deployment. They are organized in topical sections on security and QoS, WSN development and evaluation, radio and spectrum analysis, mobile WSNs, mobile ad hoc networks, and energy.
