%X In order to solve the routing holes problem of energy density routing algorithm and to balance the load of nodes in network as well as to extend network lifetimes, this paper proposed a method to divide nodes in surveillance regions according to their coupling relations, and took advantage of regional and interregional data transmissions, with different route updating frequencies in different sub-regions. Simulation shows that the new algorithm can successfully avoid routing holes and save network energy as well as prolong network lifetime.
