Due to the severe resource constraints in wireless sensor networks (WSNs), designing an efficient target tracking algorithm for WSNs in terms of energy efficiency and high tracking quality becomes a challenging issue. WSNs usually provide centralized information, e.g., the locations and directions of a target, choosing sensors around the target, etc. However, some ready strategies may not be used...
A novel flight simulator is developed which allows insects to fly actively for up to several hours in any horizontal direction, while their fall migratory flight direction can be recorded uninterruptedly. In the process of data collection and process, the CamShift algorithm combined with MFC (Microsoft Foundation Class) were used and virtual trajectory was drawn simultaneously according to the position...
In this paper, we focus on the query problem of trajectory tracking of moving targets in a wireless sensor network. Our motivation is to design in-network storage and querying protocols to support queries for searching a given target signature in a low query latency, high query reliability, and energy efficient manner. We propose a target trajectory query protocol, which combines index-based query...
We investigate the data storage and query problem for object tracking applications in wireless sensor networks. We focus on how to query the object tracking and obtain the object position effectively. The main idea is to apply multiple access entries of a storage link which stores the detected events in local storage and maintain the relation of the sensed data. When an object moves across the sensing...
In wireless ad hoc and sensor networks, each node is capable of functioning using only its local information about the environment. However, such a node can reach only locally optimal decisions that may prevent the network from ever reaching the global optimum performance for the given application. To avoid this problem, each node needs to cooperate with others to gain knowledge about the overall...
