A Self-adapted Anycast Routing Algorithm Based on Mobile Agent in Wireless Sensor Network

To reduce the transmissions among sensor nodes and prolong the lifecycle of the wireless sensor network, the immune theory and anycast technique were brought into the mobile agent routing mechanism, and an immune-based MA anycast routing algorithm was put forward. In this algorithm, the diversity and self-adaptation characters of artificial immune system were used to find out the optimal data source searching order, and then the anycast strategy was used to select a node in multiple sensing nodes of a data source. MA migrated in the nodes which was satisfied the energy conditions. The MA anycast routing mechanism was used to balance the energy consumption of sensors. Simulation results show that the proposed algorithm can reduce the energy consumption and prolong the lifetime of WSN effectively.
