Performance measurement and analysis of long range Wi-Fi network for over-the-sea communication

Currently, Indian fishermen use handheld radios or satellite phones for offshore communication. While the former is based on broadcast communication with its range limited by Line-of-Sight, the latter is expensive. Therefore, lack of connectivity-at-sea is a huge problem for many Indian fishermen. Hence,…

Optical CDMA-based wireless indoor positioning through time-of-arrival of light-emitting diodes

We propose a novel visible light wireless indoor positioning scheme based on optical-code-division multiple-assess (OCDMA) and time-of-arrival (TOA) principle. A set of three light-emitting diodes (LEDs) ceiling light fixtures are utilized to transmit their location information to a device, equipped…

Prolate-binary sequences for SLM based papr reduction in OFDM systems

To reduce the occurrence of high peak-to-average power ratio (PAPR), this paper introduces prolate-binary sequences, and their application in orthogonal frequency division multiplexing (OFDM) systems that implement selected mapping (SLM). Through computer simulation, it is shown that the proposed prolate-binary…

Endpoint protection zone (EPZ): Protecting LBS user location privacy against deanonymization and collusion in vehicular networks

In vehicular networks when map databases may be used to deanonymize user locations, we propose location based services, LBSs, be designed so that LBS users are grouped by spatial location, into endpoint protection zones, EPZs. Users in the same EPZ would share login…
