Chain-type wireless sensor network for monitoring power lines: Topology model and routing algorithm

Real-time monitoring power lines system oriented wireless sensor network, especially the chain-type, is restricted by funnel effect. Base on Ramsey theorem and MIMO technology, we give a DD Model (Diamond-shaped Double-layer Model) to solve the problem. MIMO area is a virtual multi-sink, it can alleviate congestion and reduce the transmission delay. And we use an ant colony algorithm to optimize the routing. Experimental result shows that the topology model and routing algorithm can improving the network performance.
