New approach for routing algorithm with mobile agent for reduce energy consumption in wireless sensor networks

Since Wireless Sensor Networks (WSNs) are commonly used for monitoring and controlling environments, data transmissions in these networks are done based on the content of data. One of the most renownedrouting protocols in this field is the Directed Diffusion (DD) protocol. In this protocol, gathered data bythe source nodes are transmitted to the sink. The data which is gathered from nodes is very similar, because density of the nodes is very high; therefore transmitting all them consumes much energy. To eliminate this, in network processing can be used which uses less energy to send and receive thepackets. In some methods, Mobile Agents (MAs) are used to improve the in network processing . Sink node generates MA(s) for any interest and forwards them to the network, or sends them to the source nodes that are located in the event area. The performance of these methods depends on MAs generatornodes. In this paper, a new method is presented in witch MA is generated locally in source nodes. As aresult transmissions between the sink and source nodes are eliminated, which decreases the energy consumption and increase the lifetime of the network.
