The development of modern communication technologies fosters human networks (HUNETs)-an information dissemination platform comprised of human-carried wireless-enabled devices. These networks are promising applications of delay tolerant networks (DTNs). However, existing DTN routing protocols do not address unique problems in HUNETs and are unable to utilize the benefits of human mobility. In this...
Content-based service, which dynamically routes and delivers events from sources to interested users, is extremely important to network services. However, existing content-based protocols for static networks will incur unaffordable maintenance costs if they are applied directly to the highly mobile environment that is featured in disruption-tolerant networks (DTNs). In this paper, we propose a unique...
The publish/subscribe (pub/sub for short) paradigm is used to deliver events from a source to interested clients in an asynchronous way. Recently, extending a pub/sub system in wireless networks has become a promising topic. However, most existing works focus on pub/sub systems in infrastructured wireless networks. To adapt pub/sub systems to mobile ad hoc networks, we propose DRIP, a dynamic Voronoi...
Mobile RFID systems are increasingly being deployed in industry and m-commerce. Due to the inherent limitations of mobile devices (PDAs, mobile phones, etc.) such as CPU speed, memory and storage capacity, special supports must be provided to utilize RFID in mobile devices. However, currently, most of organizations put their focuses on RFID middleware running on desktops or servers, while few attentions...
Mobility management is an important issue for publish/subscribe systems to support mobile clients. The objectives of mobility management for publish / subscribe are to achieve short handoff delay and low message overhead, while at the same time guaranteeing reliable message delivery. Although mobility management has been extensively studied, the indirect communication style of publish/subscribe systems...
