Broadcasting is one of the most important operations in the wireless network for disseminating information throughout the entire network. Flooding is a simple mechanism to realize broadcasting, but it has high redundancy of retransmissions, leading to low transmission efficiency. Many broadcast protocols have been proposed for pursuing optimized transmission efficiency for wireless networks hypothetically...
One of the fundamental operations in the wireless network is broadcasting, which is widely used to disseminate information throughout the network. Flooding is a simple method to realize broadcasting. However, flooding will incur a large number of redundant retransmissions, leading to low transmission efficiency. In this paper, we propose an optimized broadcast protocol (OBP) to improve the transmission...
In this paper, we propose a distributed event contour tracking (DECT) algorithm for multi-sink wireless sensor networks. We focus on the convex-shaped area event, which has a large effect region and may trigger many sensors at the same time. An area event may change its shape or move with time. Wild animal migration, army march, gas diffusion and chemical pollution are typical examples of area events...
