The energy conservation is the intrinsic issue of the wireless sensor network (WSN). The lack of energy of some necessary sensor nodes will affect the accurate data aggregation as well as the effective lifetime of the network. In this paper, the problem of predicting which energy level the WSNs or nodes stay in is addressed. Since the primitive method that(More)
The efficacy of topology control has been shown to be a vital process to maximize the network lifetime of wireless sensor networks. In this paper, we present a distributed topology algorithm with transmission power adjustment based on optimal number of neighbors to raise the network energy-efficiency and the network throughput by reducing channel(More)
Data mining as a novel approach has been widely applied to intrusion detection, selecting an appropriate representation to extract the most significant feature is very important, and the algorithm of pattern classification is also crucial. This paper describes a new support vector machine (SVM) for anomaly intrusion detection idea based on latent semantic(More)
In wireless sensor network, directed diffusion is a classical and data-central routing protocol, in which routing creation mainly depends on the plain flooding. For suppressing the redundant message in the flooding so as to improve its energy-efficiency, a new directed diffusion routing protocol named DDBC (directed diffusion based on clustering) is(More)
With characteristics of low-cost and easy deployment, the distributed wireless pyroelectric infrared sensor network has attracted extensive interest, which aims to make it an alternate infrared video sensor in thermal biometric applications for tracking and identifying human targets. In these applications, effectively processing signals collected from(More)
The working condition in coal mine is atrocious, once miners are stranded in coal mine when accident happened, how to find the location of the miners rapidly is the crux of rescue. This paper puts forward a wireless localization method used in coal mine which aims at the actual condition of coal mine, uses beacons and object nodes, measures the distance(More)
AODV protocol is a comparatively mature on-demand routing protocol in mobile ad hoc networks. However, the traditional AODV protocol seems less than satisfactory in terms of delivery reliability. This paper presents an AODV with reliable delivery (AODV-RD), a link failure fore-warning mechanism, metric of alternate node in order to better select, and also(More)
