Dynamic Channel Allocation Management Using Agents Technology

Abstract

Channel allocation schemes are management techniques meant to solve the radio access problem in the telecommunications area. There are several known schemes namely: static, dynamic, hybrid and flexible channel allocation schemes. In our work we developed the channel allocation scheme using a decentralized structure, based on software agents. In order to create such a structure, some functions must be carried out by some specialized functional entities. Each functional entity is implemented with an agent, having a specific role. Using this manner of implementation, different functions of the system can be implemented at different sites, located apart and also the structure can be modularized. In our work we have created the agents structure and the communications between agents, on the use of Multiagent Systems Engineering Technology. We also involved the AgentTool platform to automate the creation of the agents structure and the code resulted was in Java. In order to realize the test of our system we considered a shape of 21 radio areas, each including a number of users. Each wireless user can initiate a number of calls per hour and each call last a holding time. The communications between agents were realized for the TCP/IP protocol, based on socket connections.
