“…If the data packet is not of a high priority, the node can turn to sleep as long as the number of packets in the buffer does not exceed a predefined threshold. CACL (context‐aware cross‐layer) uses also local context related to the node density, its current state (idle, transmitting, or receiving) and the duration of the previous transmission to adjust its broadcast rate in order to avoid collisions under heavy load conditions. Indeed, upon a node n broadcasts a packet, CACL imposes a delay computed based on context data before n can broadcast again.…”

Context‐awareness has recently been considered as a viable performance leverage for adapting protocols to their deployment evolving contexts. In constrained‐based Wireless Sensor Networks (WSN), context‐awareness enables sensors to learn about their contexts and automatically adjust their behaviors to improve the overall system performance. Most of the proposed solutions, however, dealt with the optimization of the usage of resources at the MAC (Medium Access Control) level. In this regard, context‐awareness allows nodes to smartly adapt their behavior to achieve application requirements while maintaining a balanced trade‐off between resources usage and network performances. We first review the most relevant work and proposals exploiting context‐awareness at the MAC level, and then highlight the benefits of using context awareness.

“…Limiting flooding areas for improving SBSD's throughput was explored in [26]. That approach would, however, tend to reduce the gains from aggregation and filtering, as nodes would process less varied response data.…”

Efficient bandwidth usage is vital for real-time ad hoc networking applications like vehicular safety. Yet, such applications can produce large amounts of identical data. Pruning redundant data transmissions can enable delivering richer data to more users at shorter intervals. Reducing redundancy has been studied extensively for stable network topologies but the solutions are not directly extensible to dynamic topologies where information about network state obsolesces quickly. We compare two novel combinations of the adaptive controlled flooding routing protocol, SBSD, with implementations of response aggregation and query filtering for mobile environments. We test these combinations in simulated vehicular networks. We show that, even in cases where response aggregation only slightly improves network performance, query filtering can improve delivery by up to 30% and response time by 75%.
