A congestion will based constraints mechanism of mobile sensor network

A constraint mechanism of mobile sensor network based on congestion will is proposed in this paper. This mechanism can solve the problems in current constraint mechanisms that are weak to adjust the formation, lack of elasticity and flexibility. The basic principle of the constraint model is to simulate the willingness of higher organisms that maintain the space between their own to other mobile nodes or obstacles by themselves. Compared with other constraint mechanisms, this mechanism is simple, flexible, efficient, robust, and the amount of communication is small. Therefore, it can be used for the mobile sensor network which the nodes are not highly intelligent. Simulation results show that this constraint mechanism can realize cluster, fragmentation and formation maintenance of multiple mobile nodes.
