Communication infrastructure of wireless sensor networks significantly tends to depend on application requirements. Gossip communication is becoming one of the promising solutions for addressing its scalability problems in providing information propagation functionality based on the P (publish)/S (subscribe) paradigm. In particular, despite the importance of both guaranteeing message delivery order required and supporting overlapping groups in sensor networks, there exist little research works on development of gossip-style dissemination protocols to satisfy all these requirements. In this paper, we present the latest causal information transmission protocol between publishers and subscribers for overlapping groups. In this protocol, sensor leaders as publishers might guarantee consistently causally ordered message delivery among themselves by aggregating causality information. On the other hand, only the latest causal information piggybacked on each multicast message is transmitted from publishers to subscribers through gossip-style dissemination. Its scalability feature might be highly suitable for the area of the applications requiring only the minimum meaningful information.

This study suggest the development and application of the Interactive Design Toolkit as a participatory design method for general customer who are non-expert on design activity to participate in design process of mass customization. In order to let general customers to express their design needs, we have to make a familiar and direct communication method for them. And, customer's design needs should be transformed into digital media. This study define the Interactive Design Toolkit as a design tool for customer participation by direct manipulation of computer system for simulation of design needs by customer themselves. The Interactive Design Toolkit is based on a PC-based image perception system and its application. User can make virtual models in virtual space by manipulating physical objects in real world. And, The toolkit can be used in the field of participatory design for deliverer side customization, especially in system kitchen which is manufactured and distributed in modular system. More improved design toolkit for manipulating 3 dimensional shape is needed for consumer product design and car styling.
