A Queuing Model of Multi-hop Wireless Ad Hoc Network with Hidden Nodes
نویسندگان
چکیده
Hidden nodes are a basic problem that can potentially influence any multi-hop wireless networks where nodes cannot hear each other. Even though the hidden node problem is well known, its effects have not been quantified so well in a comprehensive manner up to now. This paper presents a novel framework for the queuing analysis towards getting a quantitative insight into the impact of hidden nodes on the performance of multi-hop wireless ad hoc networks by which the fundamental system limits can be obtained. Analytical expression for the probability of packet collision is first derived and using an iterative process, an M/G/1/K queuing model is developed to determine the mean packet delay, and the maximum throughput, based on IEEE 802.11 DCF model. Results are validated via simulation with statistical analysis.

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...
متن کاملThe 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...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...
