Addressing reliability and real-time issues of wireless sensor networks
a novel ant colony optimization based uneven clustering routing algorithm(ACOUC)is proposed based on Energy-Efficient Uneven Clustering algorithm(EEUC).The EEUC periodical election method is changed via ant colony optimization. ACOUC executes cluster head election and routing discovery only in the first round
and cluster adjustment and routing update instead in other rounds. The introduction of reliability and real-time indicators enables its routing establishment and maintenance more self-organizing
self-adaptive and dynamic. ACOUC lets all the nodes take part in cluster head competition
take both energy and distance as evaluation criteria to ensure the node with highest energy efficiency winning. ACOUC adopts ant colony algorithm to search the lowest cost multi-hop routing from cluster heads to sink node. The simulation shows that ACOUC performs better in energy efficiency and reliability than EEUC
