“…It may be useful, or even essential, for a message to be available to vehicles that enter the geocast region after the message has spread. In [17], three different approaches to time persistent geocast are proposed. In the server approach, the message is stored on a central server and delivered to new nodes in the geocast region.…”

Numerous protocols for geocast have been proposed in literature. It has been shown that explicit route setup approaches perform poorly with VANETs due to limited route lifetime and frequent network fragmentation. The broadcast based approaches have considerable redundancy and add significantly to the overhead of the protocol. A completely distributed and robust geocast approach is presented in this paper, that is resilient to frequent topology changes and network fragmentation. A distance-based backoff algorithm is used to reduce the number of hops and a novel mechanism to reduce redundant broadcasts is introduced. The performance of the proposed protocol is evaluated for various scenarios and compared with simple flooding and a protocol based on explicit route setup.

“…Another example is when vehicles sense a dangerous road conditions they send EWMs to other vehicles in a certain area, and these vehicles disseminate the EWMs to the new vehicles entering that area. Some of the proposed techniques are presented in (Yang et al, 2004) (Maih¨ofer, 2003) (Yu & Heijenk, 2008).…”

Energy-aware and quality of service-based routing in wireless sensor networks and vehicular ad hoc networks

Wireless Sensor Networks (WSNs) have increasingly been used for remote monitoring tasks. Limited capabilities of sensor nodes in terms of communication, computation, and storage, present challenges to protocols designed for WSNs. Due to the severe energy constraint of sensor nodes, among the major concerns is the problem of designing efficient energyaware routing protocols. Numerous routing protocols have been proposed in the literature. Cluster-based routing protocols for large-scale WSNs have some advantages as compared to a flat network topology. Clustering results in a reduced number of messages that propagate through the network in order to accomplish a sensing task. It also offers improved power control. Quality of Service (QoS) is becoming an important feature of data routing in WSNs. QoS is required for realtime data transmission when the result of a sensing task is dependent not only on the correct sensing of the environment but also on the timely delivery of the event notification to the monitoring center, the Sink.applications, for instance, impose delay requirements on the delivery of event notification messages. Transmitting video and imaging data poses certain bandwidth, delay, and jitter requirements on the routing protocols. Vehicular Ad Hoc Networks (VANETs) are envisioned to improve intervehicle coordination and become a part of intelligent transport systems with an ultimate goal of increasing safety on the roads and improving travel comfort. VANETs may include WSNs that are placed along the sides of roads and provide monitoring of road conditions. Routing protocols for VANETs also aim at satisfying end-to-end QoS requirements. This paper first discusses energyefficient clustering routing protocols for WSNs, followed by approaches aimed at satisfying QoS in WSNs and VANETS. Lastly, a discussion and comparison of features of the selected routing protocols and QoSbased approaches is presented.
