Wireless networks, especially mobile ad hoc networks (MANET) and cognitive radio networks (CRN), are facing two new challenges beyond traditional random network model: opportunistic links with random nature due to fading and dynamic channel access, and dynamic network topology due to mobility and time varying. For a more general networking of Internet users as social complex networks, such challenges...
Geographic routing is a promising approach for point-to-point routing in wireless sensor networks, but it requires the availability of geographic coordinates. Location devices like GPS do not work indoors and they are often not cost-effective for ubiquitous deployment on a large scale. While it is possible to manually configure coordinates for small sensor networks, it is infeasible to do the same...
This paper proposes an improving data fusion approach to enhance the efficient of data aggregation via Zigbee and embedded system. Distributed multi-sensor networks are an emerging technology that this study considers the problem of data fusion in wireless sensor network (WSNs) for event detection application. For such an application, maximizing accuracy and network lifetime are the two primary requirements...
A vehicular sensing network (VSN) is a type of wireless sensor network that empowers legacy resource-constrained WSNs by taking advantage of the rich network resources (e.g., the battery life, storage capability, and mobility) of vehicles. In this paper, we posit that the sensed data in VSNs is generally local in nature and propose a simple yet effective scheme, called To-and-Fro (TAF), for localized...
