The IEEE 802.11p wireless access in vehicular environment (WAVE) protocol providing for vehicle-to-infrastructure and vehicle-to-vehicle radio communication is currently under standardization. We provide an NS-2 simulation study of the proposed IEEE 802.11p MAC protocol focusing on vehicle-to-infrastructure communication. We show that the specified MAC(More)
Underwater Wireless Sensor Networks (UWSN) are faced with the challenge of estimating distances between nodes for localization purposes. To estimate the range, most researchers opt to model the propagation trajectory of an acoustics signal either as straight lines, or by solving the wave equation and then deriving the distance. The main drawback of the(More)
The dynamics, degradation, and conservation of forest ecosystems are matters of prime concerns worldwide at the present. Proper planning and management of a forest area are essentially needed to protect it from the grasp of burgeoning pressure of urban-industrial sprawl. Establishment of eco-sensitive zones (ESZs), which act as buffer areas around the core(More)
Underwater environments are categorized as inhomogeneous habitats which complicates determining long range propagation losses. Basically, transmitted signals tend to refract and change direction in accordance to the encountered sound speed profile (SSP). Therefore, a uniform spreading beam quickly loses its uniformity and complicating the estimation of the(More)
Acoustic Underwater Networks (AUNs) operate in a dynamic and inhomogeneous medium where acoustic signals tend to refract causing difficulty in sustaining connectivity and locating lost nodes. Such inhomogeneity is usually apprehended by observing sound speed variations in aquatic mediums, which is obtained by taking measurements at discrete depths, using(More)
In past few years, Vehicular Ad-Hoc Network (VANET) has seen advances in research. Content sharing through vehicle-to-vehicle communication can help people find their interested content on the road. VANETs allow peer-to-peer content distribution of data items such as traffic information, audio, video and other such information. Reliability, security and(More)
