The same result can also be achieved when optimizing F8 function (Rastrigin's function). Comparing to EGA, KEGA is easy to realize and the increase of computation load can be neglected, but the performance of KEGA can be improved greatly. 2. To enhance the speed of AIA, two new methods of computing the concentration of antibody were developed. Simulation results for F8 and F15 (needle in haystack: type I) functions show that the two methods can improve the running speed of AIA more than 8. 5 times. 3. As to the drawback in defining antibody concentration, a new definition based on Euclidean distance between two antibodies and fitness is proposed. On this basis, a new AIA was constructed. The convergence performance are more better than that of AIA. 4. Combining king crossover with AAIA and DBAIA, two new AIAs, KAAIA and DKBAIA, were proposed.

In this context, we propose a time deployment based, pairwise keymanagement scheme called TDBK. In TDBK, the network lifetime is divided intoseveral consecutive network deployment statuses which are separated by nodedeployment events. Each node to be deployed is assigned its key informationthrough a special two-tier key predistribution mechanism, and timely deletes theuseless part of the key information through the key elimination mechanism eachtime the pairwise key establishment is finished in terms of a new nodedeployment event.
