Scenario Multiparty Game
• For the scenario we chose a Server-driven game of the type Multiplayer Online First Person Shooter. (MO-FPS)– It is simpler to implement a multicast scheme
for a Server-driven game– FPS are less tolerable to latency– FPS a high rate of network traffic
6
Bluetooth and Wireless LAN
Bluetooth:• Accesspoints and Piconets
WLAN and Bluetooth multicasting:• No Acks• No reliable layer 2• Throughput• Delay

Project goals
1. Identify the features of mobile multi-party games
1. user group size
2. game session length
3. traffic volume
2. Identify the effect of the wireless environment
8
Project goals
3. Study existing multicast schemes
4. Build a test bed to validate the performance of the multicast scheme.

Choosing Scenario
Game Scenario:• A game type will be chosen. (MO-FPS)• A specific game of that type will be
selected.Test bed scenario:• A router with multicasting enabled.• Bluetooth and WLAN access points.• Computers used as nodes.
