Future Work 
Although, the work described in this thesis provides a good level of abstraction from 
low-level details in a typical LWM2M setting, there is a big scope of improvement.
The tests and results have been conducted in an environment which did not have any 
resource constraints. Further investigations are required to assess the performance of the 
LWM2M client in an actual remote, resource-constrained environment.
The ported Wakaama implementation in this thesis depends on SODAQ’s NB-IoT API. 
So, it can only be used out-of-the-box for SODAQ devices. To make it work on other 
microcontroller boards, the lower-level SODAQ NB-IoT API for uBlox modem and AT Driver 
will have to be replaced by the API of that particular manufacturer. 
Also, the AT Driver is built 
with the currently used mobile network operator 
. It will have to be modified too, if another 
operator is used. Hence, there is a scope to develop an SDK where the user can select the board 
manufacturer and operator, and the appropriate Wakaama skeleton project would be generated 
for that board. 
As investigated in Section 3.3, the code generator can be improved in multiple ways. 
Also, a provision to convert composite IPSO objects can enable the usecases that require 
intermixing of several IPSO objects.
