Distinguish, differentiate, compare and explain what is the main difference between M2M and IoT in communication protocols.
Difference between M2M and IoT
1. Machine to Machine i.e. M2M is a point-to-point communication usually embedded within hardware at the customer site. In internet of things i.e. IoT, devices communicate using IP networks, incorporating with varying communication protocols.
2. In M2M communication, many devices use cellular or wired networks. In IoT, data delivery is relayed through a middle layer hosted in the cloud.
3. In M2M communication, devices do not necessarily rely on the internet connection. In IoT, in the majority of cases, devices require an active internet connection.
4. M2M communication has limited integration options, as devices must have corresponding communication standards. IoT has unlimited integration options, but it requires a solution that can manage all of the communications.
