Secure routing issues, as a crucial research direction of security is emergent and significant in WSN The existing QoS routing protocol ignores the security design. A secure QoS routing algorithm based on ACO is designed in this paper. This algorithm combines ant colony optimization algorithm with credit evaluation mechanism effectively. In order to achieve good security performance, the creditworthiness of nodes is introduced as the control factor in antcolonyalgorithm. Firstly the algorithm will kick off the nodes which are not meet QoS needs. The set of candidate nodes will be optimized. Then an optimal route will be got by the improved ACO algorithm. The algorithm prefers the node with high creditworthiness as the next hop, thus this algorithm can avoid some attack and the optimal route has higher reliability. Finally, the security of the algorithm is analyzed from a variety of network attack.

In the research area of vehicular ad-hoc networks (VANETs), a novel notion named data-centric trust establishment is introduced recently, which means the trustworthiness of data is evaluated according to the data's intrinsic properties instead of the reputation of providing entities. In this paper, we propose a Roadside-unit Aided Trust Establishment scheme (RATE) that aims to execute data-centric trust establishment in VANET efficiently(1). Compared to existing trust establishment approaches, RATE is completely data-centric, making RATE appropriate for rapidly changing environment. In addition, through the employment of ant colony optimization algorithm, RATE has ability to integrate direct observed data with feedback information when evaluating the trustworthiness of data, eventually improves the accuracy of evaluation result. Lastly, RATE decouples data-consuming and data-providing entities, thus enables vehicles to mitigate the attacks launched by malicious nodes through directly-linked communications. Simulation shows that RATE can effectively analyze data provided in VANET and correctly establish trust on data.

This paper mainly research on the container tuck route optimization problem with the integrated loading and unloading operation. Considered the disperse-stacking of containers in yards and the loading/unloading operations of each berth, the objective function of scheduling problem is the optimal rout of the container truck. In order to solve this problem, the hybrid swarm intelligence algorithm (PSO-ACO) is proposed, which combined the particle swarm optimizationalgorithm with the ant colony optimization algorithm. The hybrid swarm intelligence algorithm takes advantage of strong local search ability of ant colony optimization algorithm and the ACO's pheromone taxis, which can avoid the particle swarm optimizationalgorithm fall in the local optimum during the convergence. The results show that the mathematical model and hybrid algorithm have effective, reliability and stability in solving the container truck scheduling problem.

In order to improve the real-time, precision and interactivity of collision detection, based on detailed study of intelligent optimizationalgorithm technology, we propose a parallel ant colony optimization algorithm, which is introduced into improved random collision detection algorithm, in preliminary testing phase we use balancing bounding box tree first to rule out disjoint objects quickly, use parallel thought[1] to accelerate the speed of collision detection, regard the basic unit and leaves of object as "ants", and then traverse the search. Compare to traditional serial and parallel collision detection algorithm and partial parallel collision detection algorithm, especially for large-scale optimization problems, in the premise does not affect the accuracy and interactivity, the algorithm accelerate the collision detection efficiency further and reduce the time complexity.

The recommendation of personalized learning paths is recognized as one of the most challenging aspects in the field of e-learning. In the existing literature, numerous approaches have been proposed to identify appropriate learning paths for e-learners, taking into consideration multiple perspectives. However, the current state of research lacks a unified framework that effectively integrates the most vital parameters associated with the learner, learning object (LO), and domain knowledge to generate optimal learning paths. To address this challenge, a novel bio-inspired approach is proposed for solving the personalized learning path problem. In this method, we initially incorporate the learner, LO and domain knowledge models into a unified mathematical model. Then an enhanced ant colony optimization algorithm is utilized to determine the optimal personalized learning paths for learners. To investigate the effectiveness of the proposed method, we performed several computational experiments based on six simulation datasets. The results indicate that the proposed method surpasses other competing methods in terms of performance and robustness, showcasing its superior effectiveness.

This paper studied the problem of parallel processing machine scheduling, taking both set up time and run-based preventive maintenance with reliability constraints into consideration. The objective is to minimize makespan. For this NP-hard problem, an antcolonyoptimization (ACO) algorithm is proposed. The node selecting probability equation is set based on characteristics of this problem. The objective value obtained by the proposed algorithm is compared to that of the classical LPT rule through numerical experiments. The experiment results imply that the proposed ACO algorithm has better performance than the LPT rule.

ant colony optimization algorithm is a novel simulated evolutionary algorithm, which provides a new method for complicated combinatorial optimization problems. In this paper the algorithm is used for solving the knapsack problem. It is improved in selection strategy and information modification, so that it can not easily run into the local optimum and can converge at the global optimum. The experiments show the robustness and the potential power of this kind of meta heuristic algorithm.

As to the power control protocol, in the CPC protocol each node uses the maximum transmit power choosed by all network nodes;the communication consumption of IPC protocol is smaller, but each node is using its own definition of transmission power, two-way link between nodes in the network can not be guaranteed. The sent power control based on data transmission can resolve the defaults of CPC and IPC.
