Interactions Between Cooperation Strategies in Mobile Ad Hoc Networks
Source: Bucknell University
Cooperation among nodes in an ad hoc network is essential for multi-hop communication. Non-cooperative or selfish nodes reduce (or cease) cooperation by refusing to forward packets for others. In this demo the authors showcase the interactions between various cooperation strategies and quantify their impact on timely delivery of traffic across multi-hop routes. The cooperation strategies are implemented under the Linux operating system and run on an ad hoc network composed of virtual nodes on multiple physical workstations. The demo includes an interactive component that allows the audience to select the cooperation strategy to run on each individual network node and observe the effects of the selected combination of strategies on network performance. The mobility between nodes is emulated from connectivity traces gathered at the 2007 MANIAC Challenge.
