The Design and Implementation of Multiterminal Based Proactive Information Delivery System

Algorithm 2

Decision algorithm of data self-adaptive process.

Input: Terminal request or user information demand

Output: Adaptive user data

(1)   Receive terminal request or user information demand;

(2)   Get terminal capability list;

(3)   Get flow and other characteristics of network;

(4)   Get user data;

(5)   Traverse user data according to data type and data node;

(6)   Check each node with capability list, if it matches terminal requirement then go to (8) else go to (7);

(7)   Check if data is suitable for the terminal, if true then go to (9) else go to (8);

(8)   Find replacement or deletion strategies and go to (6);

(9)   Adjust data according to terminal capabilities, and discard or replace if adjust to up limit, go to (6);

(10) If the adjusted package match network Qos then go to (6) else go to (11);

(11) Take strategies to adjust data, and then go to (10);

(12) Generate user data according to target file type.
