We investigate a case of automated energy-budget-aware optimization of the physical position of nodes (sensors) in a Wireless Body Area Network (WBAN). This problem has not been presented in the literature yet, as opposed to antenna and routing optimization, which are relatively well-addressed. In our research, which was inspired by a safety-critical application for firefighters, the sensor net...

In wireless sensor network (WSN), the existing intrusion detection techniques rarely consider energy consumption for judging the node state. Also there is need for increased detection rate. Hence in this paper, we propose an energy efficient intrusion detection system for WSN. Initially the nodes deployed in the network are analyzed for malicious activity based on their residual energy. If the ...

Inherent resource limitation nature of wireless sensor networks poses unique security challenges. Cryptography is not enough and efficient to secure wireless sensor networks; it can not prevent malicious nodes and tunneling of messages to wormholes and sinkholes. In this paper we propose a monitoring mechanism to detect malicious nodes; the proposed mechanism is protected with a secure triple k...

Mobile computing environment are vulnerable to malicious attacks ranging from passive eavesdropping to an active interfering. In wireless network attacks can come from all the directions and target at any node. Compensation can include leaking secret information, message corruption and node masquerade. In mobile ad hoc networks security is hard due to the dynamic nature of the relationships bet...

A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...

Wireless sensor networks have become an increasingly important area for research and application. Compared to traditional networks, its security faces many unfavorable factors such as severe resource constraints, inability to secure the wireless medium, potentially harsh sensing environment, etc. Attacks detection is an important issue to a wireless sensor network security. In this paper, senso...

Wireless sensor network consists of a large number of randomly distributed including integrated sensors, data processing and communication unit of small nodes through wireless self-organized network. Cloud computing refers to the delivery of services and the use of pattern, refers to the network to on-demand, scalable way to obtain the desired service. The paper presents development of cloud co...

This paper proposes a network coding aware QoS (quality of service) routing (NCQR) for wireless sensor network, which exploits network coding technology to improve the QoS routing of wireless sensor network. Network coding condition with QoS constraint is proposed, which provides proof for coding opportunity detection. To facilitate the evaluation of discovered routes, a novel routing metric, c...

Cloud computing is fundamental for wireless sensor network. Firstly massive data is gathered by Wireless sensor. Then those data is sent to platform of cloud computing. In the platform data is shared and transferred. The whole System is controlled and managed. In the process reliable and integrity of data depends on performance of wireless sensor Networks Topology control is one of core key fac...
