Recently, the proliferation of smartphones and the extensive coverage of wireless networks have enabled numerous mobile users to access Web resources with smartphones. Mobile mashup applications are very attractive to smartphone users due to specialized services and user-friendly GUIs. However, to offer new services through the integration of Web resources via Web API invocations, mobile mashup applications...
Data dissemination from multiple sources to mobile sinks is fundamental and challenging in WSN applications due to limited energy supply of sensor nodes and sink mobility. Previous data dissemination protocols either rely on an energy-consuming coordinate system or build an inefficient backbone. In this paper, we propose a hierarchical role-based data dissemination (HRDD) protocol in wireless sensor...
Recently, employing an in-network data aggregation forest has been proposed to achieve energy saving in wireless sensor networks with multiple sinks. The construction of an in-network maximum-lifetime data aggregation forest was shown NP-complete, and only one centralized algorithm in the literature was designed to solve it. The centralized algorithm suffers from significant control overhead especially...
