Bidirectional Parallel Mobile Agent Routing Algorithm Based On 3D Cell Space

With the development of science and technology, and the improvement of people’s living environment, Internet of things gradually catches our eyes. As the underlying technique of Internet of things, wireless sensor networks gets more attention recently, whose correlation technology obtains a degree of progress at home and abroad. Wireless sensor networks consists of numerous nodes which are deployed in monitoring areas. These nodes self-organize into a vast adaptive network according to a certain protocol, which carry the most basic sensors, microprocessors, signal transceiver, minicell and so on. And now, the development of sensor technique, wireless communication technique and computer technique enrich the function of sensor nodes. While the finite energy limits the nodes’capacity about processing and sending data imformation. So how to save energy consumption becomes an important issue of wireless sensor networks.Different with the traditional Internet technology, which uses IP address as the identification, wireless sensor networks is data-centered. So the routing protocol is very significant. In general, a mass of sensor nodes are deployed densely, which makes the information collected between nodes have strong data correlation. The clustering method can reduce data redundancy. Compared with traditional client/ server model, wireless sensor networks with mobile agent model is better at data fusion and has the advantages of low network bandwidth, strong network scalability, and high system stability.Taking advantage of cell model and mobile agent model, this paper puts forward bidirectional parallel mobile agent routing algorithm based on 3D cell space (3D-BPMA). According to this algorithm, data imformation is collected with client/ server mode among the nodes within one cell, and with mobile agent mode among cells. Migrating path of mobile agent on 3D Space is divided into several single layer cell systems. Two-way transmission permits horizontal and vertical transmission carrying out simultaneously, which improves the efficiency and reduces energy consumption. Simulation results show that comparing with other algorithms, 3D-BPMA has an effect at reducing network’s average respose time, and improving nodes survival rate and MA sending rate.
