Abstract: In wireless sensor networks(WSN)， routing is a very important factor to determine the network efficiency and energy consumption， and it is also one of the key issues for the efficient use of the network and extending the life of the whole network. In order to improve network efficiency and save energy consumption of the network as a whole， a routing optimization algorithm was proposed. To reduce the number of hops from the source node to the destination node， no connection to the neighbor node data routing was used to improve network efficiency and save energy purposes. Through comparative analysis of simulation experiments， the actual effect of the improved experimental results showed that ZigBee node routing hops and delay were reduced based on the improved routing optimization algorithm， the routing efficiency was improved， and energy consumption of the network was saved as a whole.

Key words: WSN, ZigBee, routing, neighbour node, energy conservation
