Bounds on hop distance in greedy routing approach in wireless ad hoc networks
Wireless ad hoc networks are characterized by random location of nodes, and the routes are generally multihop. A quantitative understanding of the relation between source-to-destination Euclidean distance and the hop count could provide us the knowledge about important network parameters such as granularity of localization, traffic load, end-to-end delay, delay jitter, and transmit power consum...
متن کاملA 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...
متن کاملOn the minimum hop count and connectivity in one-dimensional ad hoc wireless networks
This paper investigates connectivity in one-dimensional ad hoc networks by means of the distribution of the minimum hop count between source and destination nodes. We derive the exact probability distribution of the minimum hop count from the location density of relay nodes in the multihop path selected with the Most Forward within Radius (MFR) scheme. The probability that the source and destin...
متن کاملHop count based distance estimation in mobile ad hoc networks - Challenges and consequences
Hop Count based distance estimation is an important element for localization of devices in mobile ad hoc networks. Deriving distance estimates from hop counts is prone to error, especially in networks with low density. This paper shows that mobility can affect the accuracy of hop count based distance estimation. Two types of error are defined to describe and analyze the source of underestimatio...
متن کاملDirectional Forwarding in Multi-hop Wireless Ad hoc Networks: A Connectivity Study
Directional forwarding is useful in wireless ad hoc networks, by which the next-hop neighbors are restricted to a directional sector at a specific angle. For example, opportunistic forwarding can avoid duplicate transmissions by selecting a subset of forwarders in a certain direction. Also, emerging directional antenna design enables directional forwarding to improve signal quality, avoid inter...
