Journal ArticleDOI
DuRT: Dual RSSI Trend Based Localization for Wireless Sensor Networks
TL;DR: An RSSI-based localization scheme that considers the trend of RSSI values obtained from beacons to estimate the position of sensor nodes and achieves higher location accuracy compared with existing localization approaches is proposed.
Journal ArticleDOI
Binary-Partition-Assisted MAC-Layer Broadcast for Emergency Message Dissemination in VANETs
TL;DR: An IEEE-802.11-based multihop broadcast protocol is proposed to address the issue of emergency message dissemination in VANETs to reduce broadcast delay, which is an important factor for time-critical safety applications.
Journal ArticleDOI
Congestion-Controlled-Coordinator-Based MAC for Safety-Critical Message Transmission in VANETs
TL;DR: The proposed congestion-controlled-coordinator-based MAC (CCC-MAC), which is a time-slot-based medium access protocol that addresses beacons and emergency messages, outperforms existing MAC-layer protocols with respect to packet reception probability and latency of safety messages.
Proceedings ArticleDOI
BPAB: Binary Partition Assisted Emergency Broadcast Protocol For Vehicular Ad Hoc Networks
TL;DR: An IEEE 802.11 based multihop broadcast protocol is proposed to address the issue of safety message dissemination in Vehicular Ad Hoc Networks to reduce broadcast delay which is an important factor in time critical safety applications.
Journal ArticleDOI
Dynamic spatial partition density-based emergency message dissemination in VANETs
TL;DR: This paper analyzed and implemented a reliable time-efficient and multi-hop broadcasting scheme, called Dynamic Partitioning Scheme (DPS), which works well in both dense and light traffic scenarios and outperforms five efficient broadcasting protocols in VANETs in terms of delay and reliability.
