In this paper we are proposing an efficient secure solution to the data centric routing protocol One Phase Pull diffusion which permit multi-hop routing of sensed data. SecOPP provides both Group and Pairwise key distribution with the possibility of rekeying as well as security services: integrity, authentication and confidentiality of exchanged messages. All these are obtained without using a key...
Acoustic communication has been widely used in wireless sensor networks. Vehicle acoustic signals have long been considered as unwanted traffic noise. In this research acoustic signals generated by each vehicle will be used to detect its presence and classify the type. The goal of multiscale PCA (MSPCA) is to reconstruct a simplified multivariate signal, starting from a multivariate signal and using...
Bombs are detected by different machines and mediums but all works only under the presences of experts. They will analyze the presence and type of bombs. But this way of analyzing takes long time. In this paper, A combination of wireless sensor network supported by an expert system is the crux of the detection mechanism. Surveillance is taken care by 24X7 round the clock with effective alarming systems...
Traditional Chinese Medicine (TCM) has received considerable attention due to addressing its the real cause of the illness while western medicine treats symptoms. However, the TCM hospitals can not satisfy all those ever-increasing requirements of medical care resources when people pay more and more attention to their health conditions. In this paper, a wireless sensor-networks-based TCM system for...
Nowadays, Sensor network is extensively practical in numerous fields including general engineering, agriculture and environmental monitoring, health monitoring and surgery [1]. Sensors are designed as increasingly efficient and Miniature. As a matter of fact, the most important factor in the design of RF communications is the size of the antenna [2]. In fact, Miniaturization will be subject to steady...
Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communication capabilities. Wireless Sensor Network (WSN) is a promising data mining solution for precision agriculture.

Distributed video coding is a new paradigm for video compression based on the Slepian-Wolf and Wyner-Ziv theorems. Wyner-Ziv video coding, a lossy compression with receiver side information, enables low-complexity video encoding at the expense of a complex decoder. Most of the existing distributed video coding techniques require a feedback channel to determine the number of parity bits for decoding...
In order to achieve the best performance of a Wireless Sensor Network (WSN), it is a must to provide a challengeable routing algorithm , which consumes less power and allows more data collection. In this paper we have considered a WSN with mobile sinks and it is considered that the router follows the basic location update algorithm with traffic awareness. We show the performances of a router under...
IP-based Wireless Sensor Networks (IP-based WSNs) combine IPv6 technology with WSNs to create a global sensor network infrastructure. However, wireless radio access and Internet connectivity make end-to-end security urgently needed by security critical WSN applications. Transport Layer Security (TLS) is considered as a suitable solution to ensure such security. However, the certificate-based mechanism...
Although many studies proved that it was possible to embed application servers on a chip with limited resources, security considerations were generally marginalized. Due to their frontal position, application servers are subject to an increasing number of threats. These vulnerabilities are actually ignored in most cases mainly because of cost constraints. This paper introduces the concept of Secure...
Saving energy and prolonging network lifetime are key problem of wireless sensor networks (WSNS).
