The document discusses a proposed wireless networking architecture for smart grid applications. It first introduces smart grids and their key characteristics of being observable, controllable, automated and integrated. It then discusses existing wireless communication networks using Zigbee protocols and their challenges. The objective of the proposed architecture is to develop a wireless relay network to communicate between sensor and control networks that can find reliable links when nodes fail. It plans to use main and sub-relays to communicate between different lanes or areas.

- 3. INTRODUCTION SMART GRID •A smart grid is an electricity network that can intelligently integrate the actions of all use connected to it – generators, consumers and those that do both in order to efficiently deliver sustainable economics and serve electricity supplies. •It uses sensing embedded processing and digital communications to 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 and with the capacity to incorporate a divorce set of energy sources).
- 7. 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
- 8. CHALLENGES • Complexity • Efficiency 1) Better Telemetry 2) Faster Controls 3) More Robust Controls 4) Embedded Intelligent Device Communications 5) Integrated Communications 6) Enhanced Computing Capabilities 7)security • Reliability • Enhanced Computing Capabilities
