Contention-based geographic forwarding in asynchronous duty-cycled wireless sensor networks

In asynchronous duty-cycled wireless sensor networks, it is desirable that the data forwarding scheme is adaptive to the dynamics caused by the uncertainty of sensor nodes’ working schedules. Contentionbased forwarding is designed to adapt to the dynamic environments. In this work, we are interested in the contention-based geographic forwarding (CGF) for two asynchronous duty-cycling (ADC) mode...

Contention-based forwarding for mobile ad hoc networks

Existing position-based unicast routing algorithms which forward packets in the geographic direction of the destination require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is gained by observing beacon messages each node sends out periodically. Due to mobility, the information that a node receives about its neighb...

Contention-Based Forwarding for Street Scenarios

In this paper, we propose to apply Contention-Based Forwarding (CBF) to Vehicular Ad Hoc Networks (VANETs). CBF is a greedy positionbased forwarding algorithm that does not require proactive transmission of beacon messages. CBF performance is analyzed using realistic movement patterns of vehicles on a highway. We show by means of simulation that CBF as well as traditional position-based routing...

Cost Efficient Localized Geographical Forwarding Strategies for Wireless Sensor Networks

In this paper we investigate the relationship between local next hop selection strategies and their efficiency in terms of both link related metrics, such as the mean packet delivery fraction, and network related metrics, such as the energy status of the node elected as relay. In standard geographical forwarding algorithms the relay selection is usually carried out by means of advancements towa...

Greedy Anti-Void Forwarding Strategies for Wireless Sensor Networks

A wireless sensor network (WSN) consists of sensor nodes (SNs) with wireless communication capabilities for specific sensing tasks. Each SN maintains connectivity and exchanges messages between the decentralized nodes in the multi-hop manners. A source node can communicate with its destination via a certain number of relaying nodes, which consequently enlarges the wireless coverage of the sourc...
