An Attack-Resistant Trust Model based on Multidimensional trust Metrics in Underwater Acoustic Sensor Network

Underwater Acoustic Sensor Networks (UASNs) have been widely used in many applications where a variable number of sensor nodes collaborate with each other to perform monitoring tasks. A trust model plays an important role in realizing collaborations of sensor nodes. Although many trust models have been proposed for Terrestrial Wireless Sensor Networks (TWSNs) in recent […]

Geographic and Opportunistic Routing for Underwater Sensor Networks

Underwater wireless sensor networks (UWSNs) have been showed as a promising technology to monitor and explore the oceans in lieu of traditional undersea wireline instruments. Nevertheless, the data gathering of UWSNs is still severely limited because of the acoustic channel communication characteristics. One way to improve the data collection in UWSNs is through the design […]

Evaluation of Routing Protocols AODV, DSR and DSDV to enhance video transmission over Mobile Ad Hoc Networks

Mobile Ad hocNetworks (MANETs) are becoming more important to wireless communications due to increasing popularity of mobile devices. The main challenge for future wireless networks is the quality of service for consumer satisfaction. The tool is supporting us with instant video transmissions such as video conferences and webinars. Multiple network hops are necessary to deliver […]

SeDS: Secure Data Sharing Strategy for D2D Communication in LTE-Advanced Networks

Security and availability are two crucial issues in Device-to-Device (D2D) communication with its fast development in 4G LTE-Advanced network. In this paper, we propose a secure data sharing protocol, which merges the advantages of public key cryptography and symmetric encryption, to achieve data security in D2D communication. Specifically, public key based digital signature combing with […]

Secure and Robust Multi-Constrained QoS aware Routing Algorithm for VANETs

Secure QoS routing algorithms are a fundamental part of wireless networks that aim to provide services with QoS and security guarantees. In Vehicular Ad hoc Networks (VANETs), vehicles perform routing functions, and at the same time act as end-systems thus routing control messages are transmitted unprotected over wireless channels. The QoS of the entire network […]

High-Throughput Reliable Multicast in Multi-Hop Wireless Mesh Networks

  This paper presents a cross-layer approach for enabling high-throughput reliable multicast in multi-hop wireless mesh networks. The building block of our approach is a multicast routing metric, called the expected multicast transmission count (EMTX). EMTX is designed to capture the combined effects of MAC-layer retransmission-based reliability, wireless broadcast advantage, and link quality awareness. The […]

Enhancing Security and Privacy for Identity-based Batch Verification Scheme in VANET

  Vehicular ad hoc network (VANET) can significantly improve the traffic safety and efficiency. The basic idea is to allow vehicles to send traffic information to roadside units (RSUs) or other vehicles. Vehicles have to be prevented from some attacks on their privacy and misuse of their private data. For this reason, the security and […]

Performance Modeling and Analysis of the IEEE 802.11p EDCA Mechanism for VANET

  This paper studies performance modeling of the IEEE 802.11p EDCA mechanism and develops performance models for analyzing the access performance of the IEEE 802.11p EDCA mechanism. A 2-D Markov chain is first constructed to model the backoff procedure of an AC queue and establish a relationship between the transmission probability and collision probability of […]

Quality of service routing for multipath manets

  Adhoc network design goal is to provide internet access anytime characterized by lack of infrastructure and absence of base station, mobility and heterogeneity which require a dynamic efficient routing protocol. We proposed a delay energy aware routing protocol called as reactive congestion aware multipath routing protocol-RCRP aim to select the route based on energy […]

Local Area Prediction-Based Mobile Target Tracking in Wireless Sensor Networks

  Wireless sensor networks are spatially distributed sensors that cooperatively monitor some physical or environmental conditions. One of the key application of WSN is target tracking. In which tracking a target as it moves through a sensor network. This paper examines some of the target tracking methods in use today. During the recent years many […]
