Design and Performance Analysis of A Novel P2P-SIP Architecture for Network-Based Mobility Support in Intelligent Home Networks

Home network providers have many issues to resolve in providing home network services with an expandable, reliable, flexible, and low-cost structure to accommodate the expanding market environment. Current client-server systems have various problems, such as complexity and high costs to provide home network services. However, these problems can be simply solved by employing the P2P communication terminal that supports access of distributed resources to provide the functions that the current SIP-based network devices perform. Because diverse terminals in a home network access through networks, partitioning network domains with home gateways to manage and applying the network-based PMIPv6 (Proxy Mobile IPv6) technology that considers mobility of terminals would also help to create a more efficient home network structure. This proposed P2P-SIP architecture is very efficient with outstanding expandability to support the various home networks in a region while reducing maintenance costs.
