The data gathered shows that Malaysia has numerous smart cities that have their own goals and objectives. This has caused all the smart cities do not strive towards to national IoT goals and lead to duplication of development works. Malaysia is also the slowest progress in IoT smart cities development as compared to Indonesia and Singapore.
