Revisiting Multimedia Streaming in Mobile Ad Hoc Networks

Overview

Mobile ad hoc networks have been the subject of active research for a number of years. This paper investigates the feasibility of using such networks for transmitting multimedia streams. The paper observes that wireless network IO operations can be expensive (e.g., programmed IO cost, energy to operate wireless). Moreover, compared to nodes in infrastructure networks that either read or write network traffic, ad hoc traffic requires the intermediate node to perform many expensive network operations twice (read and then resend) and on behalf of other nodes.
