In one embodiment, cluster head finds itself to each aggregation node that can lead to based on ant colony optimization algorithm Optimal path specifically includes:
(1) cluster head e0A certain number of Front ant messages are periodically generated, another cluster in communication range is randomly choosed Head is forwarded, and starts the first timeout clock, and the Front ant message carries cluster head e0Node identification;
(2) when Front ant message δ reaches cluster head e1When, cluster head e1Selecting to probability one in its communication range does not have The cluster head of forwarded over Front ant message δ continues to forward Front ant message δ;
(3) if cluster head e1Selected cluster head e2Front ant message δ is forwarded, then to ant before the node identification of itself being added The address link list of ant message δ, updates the current ink overhead that records in Front ant message δ according to the following formula, and will before Cluster head e is sent to ant message δ2
In formula, CtIndicate updated link overhead, Ct-1Indicate the link overhead before updating, link is total when initial Expense is the unit distance link cost value that 0, C is setting,For cluster head e1With cluster head e2The distance between;
(4) continue to forward Front ant message δ according to (2), (3), until sending it to any one aggregation node;
(5) aggregation node ojReceive cluster head e0Start the second timeout clock when the Front ant message δ of generation, for The multiple cluster head e received before two timeout clocks time-out0The Front ant message of generation, aggregation node ojSelection current ink is always opened The smallest Front ant message is sold as standard Front ant message, and Back ant report is generated according to standard Front ant message Text sends Back ant message along the inverse path of standard Front ant message, and wherein Back ant message carries Address link list, the aggregation node o of standard Front ant messagejMark, link overhead;
(6) as cluster head e3Receive cluster head e4When the Back ant message of transmission, cluster head e is extracted4Node identification and convergence Node ojMark, and it is stored in local, cluster head e3Itself is updated to cluster head e4Link pheromone concentration;
(7) current cluster head continues to forward Back ant message according to the information that the address link list of Back ant message indicates, Until Back ant message reaches cluster head e0
(8) cluster head e0To the Back ant message received before the first timeout clock time-out, extracts, updates according to (6) Corresponding information, to obtain the path to different aggregation nodes identical from the Back ant message amount received;Wherein cluster Head e0A Back ant message is received, indicates the path for leading to the aggregation node that the Back ant message is recorded.
In the present embodiment, each cluster head finds itself to the optimal road for the aggregation node that can lead to based on ant colony optimization algorithm Diameter selects the smallest forward direction of current ink overhead by aggregation node when cluster head possesses mulitpath to an aggregation node Ant message generates Back ant message as standard Front ant message, and according to standard Front ant message, to ant by after Ant message is sent along the inverse path of standard Front ant message, so that for leading to the more of the same aggregation node Paths can select the smallest path of total link expense as the optimal path for leading to the aggregation node always, be conducive to prolong The life cycle of long wireless sensor network.
In one embodiment, cluster head e1Selected to probability according to the following formula in its communication range one it is not forwarded over The cluster head of Front ant message δ:
In formula, DaIndicate cluster head e1A-th of cluster head is selected in its communication range to forward the probability of Front ant message δ,Indicate cluster head e1With the pheromone concentration of the chain road of a-th of cluster head, Qa0For the initial energy of a-th of cluster head Amount, QaFor the current remaining of a-th of cluster head,For cluster head e1The distance between described a-th of cluster head; For cluster head e1Without the cluster head quantity of forwarded over Front ant message δ in communication range,Indicate cluster head e1Communicate with model Enclose the pheromone concentration of the chain road of interior b-th of cluster head without forwarded over Front ant message δ, Qb0For b-th of cluster head Primary power, QbFor the current remaining of b-th of cluster head,For cluster head e1Between b-th of cluster head Distance;t1、t2、t3It is all the weight coefficient of setting.
The present embodiment further improves probability selection formula, can more optimize the selection of next-hop cluster head, to have Conducive to the stability for improving found path, shorten path length.
In one embodiment, the more new formula of pheromone concentration is:
In formula, P (e3, e4) ' indicate updated cluster head e3, e4Between chain road pheromone concentration, P (e3, e4) it is more Cluster head e before new3, e4Between chain road pheromone concentration, y be pheromones volatility;For by standard Front ant report Text is sent to aggregation node o from the cluster head originatedjTotal hop count;Δ P is predetermined constant, indicates the letter discharged in primary update Cease the total amount of element;V is the sensor node quantity of deployment.
The present embodiment further improves pheromone concentration more new formula, so that during each Pheromone update, Each of the links increased pheromone concentration determined by the hop count in path so that the increased letter of each link in the less path of hop count It is more to cease plain concentration, advantageously allowing cluster head can be along preferably path forwards ant message relatively in the initial stage.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention Matter and range.
