Nowadays when everyone is busy using mobile devices. There are various risk involved in using mobile devices. Every communication these days are based on mobile devices. Reliability is the greatest factor. Based on reliability we have proposed reliability-based algorithm. The reliability algorithm is used to achieve the trust over the risk involved in various mobile devices. It ensures to achieve...
Now a days wireless sensors are attracting strong interest for different monitoring and controlling applications as they are integrated with the function of sensing, processing and wireless communication. The wireless sensor networks have been deployed for agricultural, industrial, remote monitoring and traffic management purposes. As energy shortage is a worldwide problem so that more attention has...
Time synchronization is very important in the IEEE802.15.4e network which aim to industrial automation applications. It enabled high end-to-end reliability and low power wireless networking. If an adversary launches time synchronization attacks to the IEEE802.15.4e networks, the whole network communications will be paralyzed. In this paper, we present two types of attacks: 1) ASN and 2) time synchronization...
In this paper, we report on the design and implementation of MBStar, a higher-frequency, real-time, reliable, secure protocol for wireless body area networks(WBAN). As in most proposals for body sensor networks, MBStar adopts the star topology for communication, and is designed to support a message rate as high as 400 Hz, which to the best of our knowledge, is the highest among low-power wireless...
Broadcasting is an important method of communication in wireless sensor network, the reliability and security of broadcast should be satisfied. Also, due to the limited resources of sensors, reducing the energy consumption is a major consideration. In this paper, we proposed an efficient and reliable broadcast protocol for clustered WSN (ERBP). In ERBP, nodes need its 1-hop neighborhood information...
With the rapid development of electronics and wireless communications technology, wireless sensor networks consisting of many wireless sensors can he used for various application fields such as military, chemical, business. Since most wireless sensor network applications have strict security requirements, security is a critical issue in wireless sensor networks. However, the new ZigBee has the security...
The following topics are dealt with: wireless sensor network; scheduling; protocols; cognitive radio; security; reliability; network coding; link layer; and telecommunication network routing.
In wireless sensor networks (WSNs), secure data aggregation is an important application. Previous works are implemented by authentication among neighboring sensors. Considering that in many cases, data aggregation is both spatial and temporal correlation, this paper proposes a distributed and localized secure data aggregation algorithm based on behavior trust (BTDA). The security and reliability of...
Wireless sensor networks (WSN) have recently achieved a great deal of attention due to its numerous attractive applications in many different fields. The focus of monitoring application is to acquire and verify information about enemy capabilities and positions of hostile targets. Monitoring applications related to security and reliability requires guaranteed k-coverage of the area at all times. A...
An important aspect of homeland security is securing public buildings and places against intrusion. Wireless sensor networks (WSN) are an efficient means of detecting intrusion and extremely convenient to deploy in such situations. However, the software running on top of the sensor nodes that directly supports the alarm applications defined by the security forces needs to provide reliability, security...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
