Mobile Ad-hoc NETworks (MANETs) are a part of the fourth generation networks vision. They are new wireless networks having transient mobile nodes with no need for a pre-installed infrastructure. They are of utmost interest for the future networks owing to their flexibility, effortlessness of deployment and related low cost. They come in two flavours: standalone MANETs and integrated with the conventional 3G network.
Providing value-added services is the core concept of several paradigms and has been extensively studied in legacy network. However, providing such services in MANETs is a challenging process. Indeed, MANETs are known for their heterogeneous devices, limited resources, dynamic topology and frequent disconnections/connections. New SIP based solutions for signalling and media handling in these networks are emerging. Furthermore, SIP is the primary protocol for 3G networks. Therefore, SIP servlets become a promising paradigm for service provisioning in MANETs.
This thesis addresses the service provisioning aspects in both standalone MANETs and integrated 3G/MANETs. The SIP servlets framework is considered as the starting point while Multihop Cellular Networks (MCNs), the widely studied networks, are used as an example of integrated 3G/MANETs.
Background information is provided, architectures requirements are derived and related work is reviewed. A novel business model is proposed for service provision in standalone MANETs. The business model defines the business roles and the relationship and interfaces between them. We also propose a service invocation and execution architecture implementing the business model. The solution is based on overlay network and a distribution scheme of the SIP servlets engine. The overlay network enables self-organization and self-recovery to take into account MANETs characteristics. As for the integrated 3G/MANETs we propose high level architectural alternatives for service provisioning in MCNs. We identify the most interesting alternatives from the network operator point of view and proposed a detailed and concrete architecture for the promising alternative. Overall architecture, functional entities and procedures are presented. During this work, we built prototypes as proof-of-concept and made preliminary performance measurements, used SPIN as protocol validation tool and adopted OPNET for simulation. The results show that we can provide services in MANETs as we do in conventional networks with reasonable performance.
