Agent-Based Location Aware Services in Wireless Mobile Networks

As mobile devices and third generation mobile networks have become a reality, location based services are thought to be a major growing area. Mobile devices are given context sensitiveness so that they can be aware of the users/services surrounding physical environment and state. In this paper we propose location aware services scheme by using an agency, which helps in discovering the required services for the mobile users. The agency consists of five agents: manager agent (MA), route monitoring agent (RMA), local service management agent (LSMA), global service management agent (GSMA) and area monitoring agent (AMA). Agency can manage services in case of service breakdown, node and link failures. The proposed scheme is simulated and tested for different network topologies by considering different mobility scenarios. It is observed that agency offers flexible and adaptable services.
