DSR-Based Directional Routing Protocol for Ad Hoc Networks

DSR-Based Directional Routing Protocol for Ad Hoc Networks

In this paper, a Dynamic Source Routing (DSR)-based directional routing protocol is invoked for wireless ad hoc networks using directional antennas. This is designed to balance the trade-off between co-channel interferences from nodes hops away, and the

Sources of Uncertainty for Near-Field Measurements

Sources of Uncertainty for Near-Field Measurements

We discuss the sources of uncertainty in near-field measurements and their impact on far-field antenna parameters. The methods of estimating these uncertainties can be considered in three broad categories: theoretical estimation (analytical), computer

Fair Bandwidth Sharing under Random Flow Arrivals/Departures: Metastability & Flow Admission Control

Fair Bandwidth Sharing under Random Flow Arrivals/Departures: Metastability & Flow Admission Control

Flow-level performance of fair bandwidth sharing protocols under random flow arrivals/departures is not sufficiently understood due to intractability of the corresponding Markov model for realistic-size networks. Tractability of the Markov model in fluid

Metastability of Fair Bandwidth Sharing Under Fluctuating Demand and Necessity of Flow Admission control

A flow-level Markov model for fair bandwidth sharing with packet retransmissions under random flow arrivals/departures is proposed and discussed. Fluctuations in the numbers of flows in progress cause the network instability even under light load. The
