In this paper, the hierarchical architecture of the sensor network (MESH-network) with a high degree of scalability is proposed. The possibilities of its realization in the mode of self- configuration using the special routing protocol at the query (AODV — Ad-hoc On-Demand Distance Vectorisation) and fixed-line routing protocol (OLSR — Optimised Link-State Routing) are investigated. The comparative analysis of radiosensors networks that function after the algorithm of mobile agents, and networks that function after the algorithm of mobile agents with directed diffusion of data stream from knots-sources to the knot receiver, is executed. It is shown that for applications, where the energy consumption has a primary importance using of mobile agents with the directed diffusion allows considerably to prolong the life cycle of network. Technologies of mobile software agents with optimisation modules and autoconfigurations increase network bandwidth, reduce transmission delay and load on the network, reduce the traffic of HELLO messages in accordance with the scalability of the network. On the basis of theoretical estimates and simulation results, it can be concluded that the application of adaptive tuning mechanisms increases the performance of the protocols OLSR and AODV in comparison with the analysed basic protocols.
The developed methods allow to create the mechanism of diminishing of loading on the separate links of network due to balancing of packages at a decision-making about routing. In theory it is possible to use offered approach for a decision-making about routing of packages in a network on the stack of TCP/IP protocols.
