2017 IEEE 6th Global Conference on Consumer Electronics, GCCE 2017 2017- 1 - 2 2017.12

To advance Java programming studies, we have developed the Java Programming Learning Assistant System (JPLAS). The test code plays a critical role in verifying the correctness of the source code from a student automatically at the server in the code writing problem in JPLAS. Previously, we proposed the test code generation tool that automatically generates the test code from the given source code containing standard inputs/outputs that novice students are expected to study in advance. In this paper, we extend this tool to handle the source code with file inputs/outputs. By applying the extended tool to three codes containing file inputs/outputs, the correctness of the generated test codes is confirmed.

A holding access-point assignment algorithm for wireless local-area networks

Shigeto Tajima, Nobuo Funabiki, Sumon Kumar Debnath, Teruo Higashino

2017 9th IEEE International Conference on Communication Software and Networks, ICCSN 2017 2017- 367 - 371 2017.12

Language：English Publisher：Institute of Electrical and Electronics Engineers Inc.

Nowadays, various types of access-points (APs) and hosts such as dedicated APs, laptop personal computers, and mobile terminals have been used in IEEE802.11 wireless local-area networks (WLANs). As a result, the optimal assignment of holding APs into the network field depending on the host type distribution has become very important to improve the network performance. In this paper, we formulate this holding access-point assignment problem as a combinatorial optimization problem and propose its heuristic algorithm. Because plural non-overlapping channels are available in IEEE802.11 WLANs, we extend the algorithm to finding the channel assignment to the APs such that the total interference among them is minimized. The effectiveness of our proposal is verified through simulations in three instances.
