A Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks

Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...

The Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks

Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

Interaction between TCP and UDP flows in Wireless Multi-hop Ad hoc Networks

The interaction between TCP and UDP flows are examined experimentally in simple scenarios, involving between three and four nodes. Early results show that TCP’s congestion control is not tuned to wireless multi-hop settings, resulting in significant jitter and loss in UDP flows.

Broadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach

While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...

TCP performance in multi-hop wireless ad hoc networks: challenges and solution

Transmission control protocol (TCP) performance over multi-hop wireless networks is currently attracting considerable interest from the research community. The characteristics of multi-hop wireless networks, such as mobility, link layer contention, high bit error rate, asymmetric path, network partition, hidden exposed nodes and dynamic routing, do not fit the requirements of TCP for a good rel...
