Multi agent system based service architectures for service level agreement in cellular networks

To provide Service Level Agreement (SLA) in wireless cellular network the network provider needs to do resource management through call admission and channel allocation strategies. Also if the SLA is unsatisfactory it has to react rapidly to reinstate the promised quality of service (QoS), provide alternatives or do congestion control. Our Paper proposes two Multi Agent System based, Centralized and Distributed, Service Architectures for SLA management. We extend the SHUFFLE model by introducing Network Provider Cell Agent (NPCA) which works in collaboration with Network Resource Provider Agent. Dynamic Call Admission is implemented using NPCA - NPCA interaction to accommodate real time traffic. The Agent are implemented using open source Java Agent DEevelopment Framework (JADE). The results of Multi agent and Non agent based connection level parameters are compared to understand the overhead characteristics of the systems.
