Mobility Support for Wireless Sensor Networks

This work proposes a two-tier approach for mobility support in wireless sensor networks. It is based on local interactions among sensors, on global tasks of mobile agents and on location prediction. We demonstrate the correctness of a simple location prediction model. We also propose, evaluate and compare two algorithms for mobile agents decision. The proposed scheme is stateless and does not need a routing protocol. All computing (location prediction and mobile agents decision) are of linear complexity. We observed a better performance as mobility degree and node density grow.
