摘要：
For the limited processing, storage and energy of network nodes in the wireless sensor network environment, a distributed JPEG2000 coding algorithm based on mobile agent is proposed. Multiple network nodes are utilized to the image distributed coding and mobile Agent mechanism is used to communicate among network nodes. The energy consumption of single node is reduced under the invariant coding performance of the image, thus prevents the system from paralysis caused by the energy depletion of single node and prolongs the life cycle of the system. Simulation results show that the proposed algorithm is better communication capability of network nodes while the quality of the image is invariant after the coding, and can achieve a good balance of the network energy consumption and prolong the network life cycle 3 times as before.
