  • For that the communications by unreliable links wastes too much energy in wireless sensor networks, based on link quality, routing cost functions are constructed and proper selective probability is allocated to paths. Then the algorithm CBLQ (Cost Balanced routing algorithm based on Link Quality) is designed by adopting the minimum-hop-count forwarding strategy. To further reduce and balance the routing costs, the alternate forwarding condition of brother nodes is analyzed and the new routing algorithm, CBLQ-E, is extended to form. The results of simulating experiments prove that both algorithms increase the ratio of energy utilization effectively, as well as decrease the data transmission delay of networks.
