INTRODUCTIONSMART GRID

•A smart grid is an electricity network that can intelligentlyintegrate the actions of all use connected to it – generators,

consumers and those that do both in order to efficiently deliversustainable economics and serve electricity supplies.

•It uses sensing embedded processing and digital communicationsto enable the electricity grid to be

Observable (able to be measure and visualized)

Controllable (able to be manipulated and optimized)

Automated (able to adapt and self-heal)

Fully integrated (fully interoperable with existing systems andwith the capacity to incorporate a divorce set of energy sources).

Different consumption areas

EXISTING COMMUNICATION NETWORK

Wireless Sensor Network• Communication via Zigbee protocol stack

– IEEE 802.15.4 standard• Low power

– Duty cycles• Low data rate

– Data rates of 250 kbps, 100kbps, 40 kbps and 20 kbps• Zigbee utilizes three ISM bands

– 2.4GHz ISM band worldwide , 915MHz band in North America, 868MHz band in Europe

• Zigbee uses 16-bit and 64-bit addressing modes– 6lowpan for IP integration

• Star, cluster-tree or mesh topologies

CHALLENGES

• Complexity• Efficiency

1) Better Telemetry2) Faster Controls3) More Robust Controls4) Embedded Intelligent Device Communications5) Integrated Communications6) Enhanced Computing Capabilities7)security

• Reliability• Enhanced Computing Capabilities

LITERATURE

WIRELESS SENSOR NETWORK VS

WIRELESS RELAY NETWORK

By introducing wireless relay network,

• Brings down the number of sensors in network.

• Reduced Power consumption.

• Node failures can be identified easily.

• Data of desired lane or avenue can be easily accessed.

• Low installation cost.

OBJECTIVE

The objective of this project is to accomplish a wireless relay in communication between sensor and control area network and

finding reliable link, when next hope node fails in communicating.
