The recent growth of high speed wired/wireless access and LANs, functional wireless terminals such as smart phones and tablets, and cost-effective sensor/tag devices increasingly stimulate the emergence of user-centric network services collecting and exploiting user-provided data. Monitoring and notification system of children or elderly people using sensor data is such an example. In order that the networks support these services in the flexible and scalable manners, multihop/relay technique involving user terminals will play a key role. From this perspective, mobile ad hoc and mesh networks, sensor networks and P2P networks have been attracting much attention. These networks typically consist of autonomous nodes without any central control and they should be self-organizing to handle the growing complexity of the upcoming networks and to adapt to unpredictable change of the network environments. Distributed topology management, resource management and routing are common research challenges in all these networks. The objective of this Workshop is to discuss new approaches and technologies in the field of ad hoc and mesh networks, sensor networks and P2P networks through papers. Particularly, we welcome papers describing protocol designs or performance evaluations both from theoretical and practical aspects, or describing observations and findings from practical experiments.
