With the enlarging demand of material culture,the technique of wireless sensor networks(WSNs),which was initially facilitated by military requirement,is being penetrated in all sides of the social life,including medical,agriculture,household,industry,environmental protection,transportation.Perfectly integrating wireless communication technique and sensor technique,wireless sensor networks improve continuously with the rapidly development of micro electro mechanical system(MEMS),embedded system,signal processing,and automatic control technology.In a wireless sensor network,a large number of functional microsensor nodes were intensively deployed within the surveillance area according to application requirement.These nodes would collect and converge useful messages,and then transport them to the control center who would dispose these messages.In this course,there will be various uncertainties and available room to be optimized.The optimization scheme of routing and the saving scheme of energy consumption are both research hot spots.The amount of sensor nodes of WSNs is considerable,and all of these nodes are energy limited.According to WSNs' characteristic,researchers have been exploring optimized transmission strategy to prolong network's lifetime,to enhance messages'accuracy and real-time.The applying of mobile agent technology is a breakthrough of the research of routing protocol and energy-saving strategy.With mobile agents,networks' scalability and stability could be improved.What's more,mobile agents are able to make the utmost of sensor nodes' data integration,to help reducing transmission energy consumption.Aimed at the problem of mobile agents' two-way transports in one space model,this text puts forward an algorithm named "parallel mobile agent energy efficiency routing based on 3D cell space(3D-PEMA)".This algorithm puts forward integration criterion to estimate the necessity of executing data integration during mobile agents'visiting.In the monolayer system of cell space,the traversing method of single-MA and multi-MAs are put forward to compare their energy consumption.And the two methods are combined suitably to optimize horizontal transmission.The simulation result shows that compared with 3D-BPMA and MIP algorithm,3D-PEMA comes up with shorter average responding time and lower average energy consumption.
