Wireless sensor networks (WSN), sometimes called wireless sensor and actuator networks (WSAN), are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional, also enabling control of sensor activity. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance; today such networks are used in many ....etc

ABSTRACT

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Position based routing protocols are becoming popular due to advancement and availability of GPS devices. One of the critical issues of VANETs are frequent path disruptions caused by high speed mobility of vehicle t ....etc

The limited built-in configurability of Linux can lead to expensive code size overhead when it is used in the embedded systems application. This problems can be overcome by the use of the link-time compaction that exploit the previously well known fixed runtime environment of many embedded systems. The ARM XScale and i386 platforms are used as the test platforms and with the proposed method, upto 16% reduction in the kernel memory footprint can be achieved. The proposed techniques can be implemented easily with simple additions to existing bina ....etc

ABSTRACT
Open-access distributed systems such as peer-to-peer systems are particularly vulnerable to Sybil attacks, where a malicious user creates multiple fake identities (called Sybil nodes). Without a trusted central authority that can tie identities to real human beings, defending against Sybil attacks is quite challenging.
Among the small number of decentralized approaches, our recent SybilGuard protocol leverages a key ....etc

Detecting and Locating Wormhole Attacks in Wireless Ad Hoc Networks


Abstract:
Wireless communications offer organizations and users many benefits, such as portability, flexibility, increased productivity, and lower installation costs. Wireless technologies cover a broad range of differing capabilities oriented toward different uses and needs. Wireless local area network (WLAN) devices. Ad hoc networks, such as those enabled by Bluetooth, allow data synchronization with network sys ....etc
