Home Engineering Modeling and Optimization for Mobile Social Networks
The nodes in MSNs are electronic devices that have limited resources, such as buffer, energy, etc. Mobile nodes would exhibit selfishness to save their own resources. The node model is summarized as follows.
When a source node Src sends a message M to a destination Dst, Src first sets the message head with necessary information and then generates a bundle, as shown in Fig.4.2.
Specifically, the bundle is comprised of six components: its bundle sequence number ID, source Src, destination Dst, creating time stamp TS, time-to-live TTL, and message M.
Fig. 4.2 Formation of the bundle
Our design goals have two desirable objectives as follows: On one hand, our scheme should be effective in stimulating selfish nodes to participate in bundle delivery in MSNs. On the other hand, it should be efficient without introducing too much extra transmission delay.
