A Novel Service Discovery Mechanism in MANET Using Auto-Configured SDA

The paper proposes a novel service discovery mechanism for mobile ad hoc networks (MANET). The mechanism follows the manner of dynamically setting up service discovery area (SDA) managers in MANET, which are responsible for centralized service repository and service requests processing. SDA overlap among multiple SDAs is detected on the fly and an algorithm is proposed to calculate overlapped area percentage, based on which eliminable SDA is figured out and eliminated. Proposed mechanism provides scalability to large MANET and can work efficiently without manual monitoring and management.
