Mobile Peer-to-Peer Network Architectures

Matt Monroe4/7/11

Client-Server Model Clients connect

directly to a central server

All communication between clients happens by communicating with the central server

Problems With Client-Server

Network Bottleneck Server Overload High Latency Inefficient Bandwidth Use

Peer-to-Peer Network Basics

Allow Clients to connect to each other directly

More Efficient Lowers Latency

Peer-Client-Server Model Clients can

communicate with other clients directly

Clients also communicate with remote server

Problems with Peer-Client-Server

Server Overload Not Resolved Single Point of Failure Still high latency if remote server is used

heavily

Super-Node Model Clients form sub-

networks Sub-networks

controlled by a ”Super-Node”

Super-Nodes connect together sub-networks

Problems with Super-Node Super-Node clients could have poor

experience Critical Mass Issue Data Distribution Higher Development Cost

Fully-Distributed Model Clients connect to

other clients near them

All clients are equal

”Truly” Peer-to-Peer

Problems with Fully-Distributed

Critical Mass User Base High Development Effort Useless in Low Population Density Areas Data Distribution
