Performance and implementation of routing and wireless transport layer connections in micro mobility Ad hoc networks

In English In mobile ad hoc networks wireless nodes communicate over multi hop links and are capable of movement. This paper evaluates a solution that provide these networks with Internet Access and the capability to roam between different access points. Design and implemenation consideration are discussed that focus on behaviour and criterias for performing handover. Simulation result show that the main factor affecting transport performance during micro mobility are link breaks, where choice of TCP flavour and advanced window freezing behaviours have little effect It is also shown that a new kind of TCP unfairness arise when different TCP flavours compete among each other.
