1.3 Network Types and Characteristics in Focus

----------------------------------------------



(a) "Mobile Adhoc networks (MANET) are self-configuring

    _infrastructureless_ networks of mobile devices connected by

    wireless technologies."



    --> Why is a differentiation being made between MANETs and other

        types of wireless networks? Couldn't moblie phones technically

        fit into the IoT as well? Is the differentiation only made

        based on the _infrastructureless_ part of it? If so, does it

        make sense to have categories of infrastructure and

        infrastructureless, rather than MANET and non-MANET networks?

    

(b) "Wireline non-constrained networks are mainly used for specific

    applications like Building Automation or Infrastructure

    Monitoring.  However, wireline and wireless networks with

    multi-hop or point-to- multipoint connectivity are especially in

    the interest of the analysis on the management of constrained

    devices in this document."



    --> This paragraph is unclear. What is it trying to convey? Is it

        saying that only wireline multi-hop and point-to-multipoint

        are within the scope of this document? Why not regular

        wireline networks that may have constrained devices as part of

        a non-constrained network?

    

    --> There is talk about bandwidth, but not frame size, which is

        likely to have a bigger impact than the overall bandwidth

        available in a channel. Maybe this should be mentioned?





1.6.  Managing the Constrainedness of a Device or Network

---------------------------------------------------------



(a) "might only be able to support one simple communication protocol,

    i.e. the management protocol needs to be possible to downscale

    from constrained (C2) to very constrained (C0) devices"



    --> Is it important that the same management protocol be

        applicable to the entire range of constrained devices? Why not

        allow the capabilities of the management protocol to scale up

        and down with the type/capabilities of the device at hand?



	SOLUTION: A new bullet point stating that different management

	protocols work on different class of devices.



(b) "might only be able to support limited or no user and/or transport

    security" AND "might only be able to support very simple

    encryption"



    --> Simple encryption doesn't make sense, maybe it should be

        efficient encryption instead?



(c) "might also need energy-efficient key management algorithms for

    security."



    --> Not just energy-efficient, but also memory, processing and

        etc. efficient. No?



	SOLUTION: Change text to only efficient key management.
