Internet of Things & M2M

Internet of Things– Towards a vision of networking ‘Things’ on Internet– Practically it signifies

o Sensing, Identifying, communicating between physical objects such as home appliances, furniture, vehicles, buildings, components of infrastructures such as roads, utilities and many more…

Machine to Machine (M2M) communications is a part of the above vision

Challenges in Actuating Things

Actuation causes a change in the state of things (can be catastrophic if in-appropriate)

Actuation has associated responsibility– Need authentication, – Timeliness, robustness– Security against un-intended actuations

Action may be triggered by a software agent or human being. Challenges in trusting a software agent.

Energy saving and autonomic capabilities Cooperative Actuation further these challenges

Erasure coding for Robust Protocol

Erasure Coding: k blocks are encoded to n blocks , introducing (n-k) redundancy. If the number of blocks lost during the transmission m <= (n-k), then original information can be recovered.

Mostly used technique to address packet losses is retransmission. This creates un predictable delays and reduced throughput.

Erasure coding is an alternate way to address this. An apriori estimate of the channel condition can help in planning the redundancy required.

From an IoT perspective, this would be impactful for multicast transmissions ( mass upgrade, mass configuration etc)

Evaluation Robust CoAP is in progress

Identity based Encryption for Secure IoT

Identity based Encryption system– Here a public key is derived from Identity – Unlike PKI there is no key exchange required during

transactions

In IOT/M2M the number of devices involved are too many. Key management and exchange would be an issue

IBE can be used in such cases. Private keys are embedded in the device. Public key is derived from publicly known identities such as IP address, MAC address, URI etc.

Robots as Mobile Gateways

Mobile data collection– Agriculture monitoring– Mobile Agro-advisory System– Real-time sending of Soil Temperature, Soil Moisture,

Atmospheric Temperature and Atmospheric Humidity

Advantages of Robots as Mobile Gateways– Energy saving through lower communication range– Periodic Sensor auto calibration

18

Technology Challenges

Wireless Networking– Variable communication range– Mobility: no to moderate (pedestrian) speeds– Dynamic topology– Reliability & robustness, security– Real-time communication for actuation (downlink)
