MP2P Based on Social Model to Serve for LBS

In a social network, nodes and links represent participants and their friendships respectively, and many applications also have this character. When tourists are traveling, they usually want to get the help of Location Based Services (LBS). However, the charge for using LBS is so much that there are few people could accept this new consumptive method. We take note of that the information, required by tourists coming from the same group with heterogeneous communication equipments, usually focuses on a certain area. So we propose the mobile peer-to-peer (MP2P) technology built on the social network model. MP2P network can let message be transferred among neighbors instead of in the whole communication system, and this could save information in a group and meet the need for the other tourists through storage and transmitting. So the tourists could cut down the fee of using LBS.
